No Minimum Order Fasteners: How to Buy Small Quantities from China

Q: Can I really order just one screw?

Yes, for stocked standard parts. A single M3 x 10 socket head cap screw can be ordered and shipped; the constraint is not the part but the freight, which has a minimum chargeable weight. Expect the shipping cost to exceed the part cost by a wide margin on a one-piece order.

Quick answer

“No minimum order” means the supplier does not require a minimum quantity per line item or per order — you can buy one piece. In practice, most suppliers who advertise no MOQ still sell in pack quantities (10, 50 or 100 pieces) and still have a minimum freight cost that dominates small orders. A genuine no-MOQ supplier lets you buy a single piece, shows the pack unit before checkout, and prices freight separately so you can see the real landed cost.

What “no minimum order” actually means

The phrase covers four different commercial models, and suppliers rarely say which one they mean. Before comparing quotes, establish which model you are being offered.

Model	What it means	Where you meet it
No MOQ per line	Any quantity of any single part, but the total order may carry a floor (e.g. USD 50)	Most common on B2B sites
No MOQ per order	No floor at all; a USD 8 order is accepted	Online stockists, catalogue distributors
No MOQ, pack quantity only	No order floor, but each part is sold in 10/50/100-piece packs	Very common in China-based catalogues
True single-piece	One piece of one part, priced per piece	Rare; usually limited to small parts

For a design engineer prototyping an assembly, only the last two are usable — and of those, only true single-piece pricing tells you the real cost of a prototype build. For a buyer restocking a bin, pack quantity is fine and usually cheaper per piece.

The question that settles it: “Is the price per piece, and can I order one piece of this part number?” Ask it in writing. A supplier who answers with a dimension table and a price rather than a MOQ policy is telling you something useful.

Why most suppliers set a minimum

Minimums are not arbitrary. They cover four real costs:

Order handling — picking, counting, packing and paperwork cost roughly the same whether the order is 1 piece or 10,000. At one piece, handling exceeds the part value.
Packaging — a bag label, an inner bag and a carton have a floor cost.
Freight — international small-parcel has a minimum chargeable weight. Below roughly 0.5 kg, you pay for air you are not using.
Setup — for non-stock or made-to-order parts, machine setup is amortised over the batch. This is the one minimum that cannot be removed by a stockist; it can only be avoided by choosing a stocked standard part.

This is why “no minimum order” is a stock proposition, not a manufacturing one. If a supplier offers no MOQ on a made-to-order special, either the setup is already absorbed in a higher unit price, or the MOQ will reappear at quotation stage.

What you can realistically buy in single pieces

Availability depends on how the part is stocked. The table below reflects what is normally available at piece-level from a China-based stockist catalogue.

Part family	Single piece realistic?	Notes
Micro screws M0.8–M3 (GB 818, GB 845, DIN 912)	✅ Usually yes	Sold loose or in small packs; the most common prototype purchase
Socket head cap screws M3–M12 (DIN 912)	✅ Yes	Standard stock item worldwide
Hex bolts M1.6–M8 (DIN 933)	✅ Yes	M1.6–M3 sizes are the differentiator; below M3 is hard to find locally
Hex nuts, washers (DIN 934, DIN 125, GB 96)	✅ Yes	Rarely worth ordering alone — freight exceeds value
Retaining rings / circlips (GB 896, DIN 472)	✅ Yes	Small diameters Φ1.2–Φ5 are the low-competition segment
Hex standoffs (M2, M3, M2.5)	✅ Yes	Electronic assembly quantities are naturally small
Rivet nuts M3–M8	⚠️ Usually packs of 10–100	Piece-level possible but rarely economic
Threaded rod (DIN 975)	⚠️ Sold by length	Ordering 100 mm of M3 rod is possible; freight dominates
Special / non-standard parts	❌ No	Setup cost; expect a real MOQ at quotation

Rule of thumb: the smaller the part and the more standard the specification, the more likely single-piece purchase is economic. The heavier or more specialised the part, the more the freight and setup costs pull you back toward a batch.

How to buy small quantities from China: six steps

Step 1 — Write the specification the way the supplier reads it

Ambiguity is the main cause of wrong shipments on small orders. A complete line item carries six fields:

Field	Example	Why it matters
Standard	DIN 912 / GB/T 70.1 / ISO 4762	Defines every other dimension
Thread × length	M3 × 10	Length definition differs by standard (see Step 2)
Material grade	A2-70 (304) / A4-80 (316) / 8.8 steel	Drives strength and corrosion
Finish	Plain / zinc plated / black oxide	Drives appearance and corrosion
Tolerance class	6g (default for metric threads)	Rarely stated, often assumed
Quantity + unit	50 pieces (not “50”)	Prevents pack-vs-piece confusion

Step 2 — Confirm the standard equivalent before you order

If you are buying from China against a European drawing, the part is very often specified in GB (Chinese national standard) rather than DIN or ISO. A DIN 912 socket head cap screw and a GB/T 70.1 screw are dimensionally equivalent, but not every family maps so cleanly — head heights, thread lengths and tolerances can differ by family.

The practical move is to check the mapping before requesting a quote, and to write both standard numbers on the purchase line. This is the single highest-value five minutes in cross-border fastener sourcing, and it is why we publish a full GB vs DIN vs ISO comparison chart covering 34 fastener families.

Common pairs worth memorising:

Family	China (GB)	Europe (DIN / ISO)	Fully interchangeable?
Hex head bolt, full thread	GB/T 5783	DIN 933 / ISO 4017	Dimensionally yes
Hex head bolt, partial thread	GB/T 5782	DIN 931 / ISO 4014	Dimensionally yes
Hex nut	GB/T 6170	DIN 934 / ISO 4032	Yes for standard heights
Socket head cap screw	GB/T 70.1	DIN 912 / ISO 4762	Yes
Cross recessed pan head machine screw	GB 818	DIN 85 / ISO 1580	Head height and recess depth can differ
Flat washer	GB/T 97.1	DIN 125 / ISO 7089	Yes
Internal circlip	GB 896	DIN 472	Check groove dimensions before substituting

Step 3 — Establish the pack unit, not just the price

The same part can be quoted at USD 0.02/piece in a 1,000-piece pack and USD 0.08/piece for a single piece. Neither quote is “wrong” — they are different products commercially. Always confirm:

Is the quoted price per piece or per pack?
What is the pack quantity of the SKU I am looking at?
Does the cart multiply by pack or by piece?

Step 4 — Calculate the landed cost, not the unit price

At small order values, freight is the dominant cost, and it is the number buyers most often ignore until checkout.

Order value	Illustrative freight	Freight share of landed cost
USD 20	USD 18	47%
USD 50	USD 20	29%
USD 150	USD 28	16%
USD 500	USD 55	10%

(Illustrative arithmetic, not a quote — actual freight depends on chargeable weight, destination and service level. Our checkout calculates freight before payment, so the real figure is visible before you commit.)

The implication for prototype buying is counter-intuitive: it is often cheaper to place one slightly larger order than three small ones, because each additional small parcel carries its own freight floor. Consolidate.

Step 5 — Ask for a proforma invoice, not just a price list

A proforma invoice does three things a price list cannot: it fixes the unit price and quantity in a document your finance team can approve, it carries the HS code and description your customs broker needs, and it creates a written record of the standard number and material grade you agreed.

Every order at SFX generates a proforma invoice automatically — see How to order for the flow.

Step 6 — Make the order repeatable

Small-order sourcing becomes expensive when each purchase is a fresh negotiation. Record the specification (six fields above), the standard mapping you confirmed, and the pack unit. Next time, the order is a part number plus a quantity, and a different colleague can place it without rediscovery.

What to check before you place a small order

Length definition — for socket head cap screws, length is measured from under the head; for countersunk screws, it is overall length including the head. A 1 mm error here is a scrapped prototype.
Thread pitch — M2 × 0.4 coarse vs M2 × 0.25 fine are different parts with different availability. Fine pitch in tiny sizes is a specialist item.
Head marking / grade — 8.8, A2-70 and A4-80 look identical in a photograph and behave very differently in service.
Material certificate — ask whether the lot can be supplied with a material certificate before you order; after shipment it is usually too late.
Plating specification — “zinc plated” covers trivalent blue, white and yellow; state which, or state the corrosion hours you need.
Piece vs pack in the cart — check the quantity unit on the cart line, not on the product page.
Who pays duty and import VAT — on small parcels this can exceed the goods value in some jurisdictions. Confirm the Incoterm in writing.

When not to buy small quantities from China

Honest boundaries matter more than a sales pitch, so:

If you need more than a few thousand pieces of a standard part, buy locally or negotiate a container-level price — the freight and duty structure flips in favour of volume.
If the part is safety-critical or requires PPAP / IATF-level documentation, small-quantity cross-border sourcing is the wrong channel.
If you need it this week, air small parcel from China is typically days, not hours, and customs can add unpredictable time. Keep a local buffer for line-down risk.
If the part is heavy (large anchors, long threaded rods), freight per piece usually erases the unit-price advantage below a certain order size.

Being clear about this is what separates a supplier you can use repeatedly from one you use once.

FAQ

Can I really order just one screw?

Yes, for stocked standard parts. A single M3 × 10 socket head cap screw can be ordered and shipped; the constraint is not the part but the freight, which has a minimum chargeable weight. Expect the shipping cost to exceed the part cost by a wide margin on a one-piece order.

What is the difference between no MOQ and no minimum order value?

No MOQ refers to quantity per item. No minimum order value refers to the total cart. Many suppliers offer the first but enforce the second (commonly USD 30–100). Confirm both, in writing.

Why is the unit price for 1 piece so much higher than for 1,000 pieces?

Because handling and packaging cost the same regardless of quantity, and at one piece those costs are not spread over anything. The 4× gap between piece price and bulk price is normal, not a markup applied to punish small buyers.

Do I need a company to buy small quantities from China?

Not usually for stock catalogue parts — a private individual can order. You will need a company for trade terms (Net 30, volume pricing) and for tax deduction of import VAT in most jurisdictions.

How long does shipping take for a small fastener order?

It depends on the service chosen, not on the order size. Express courier, air parcel and consolidated freight have very different transit times; the trade-off is cost against speed. Confirm the service level per order rather than assuming a fixed lead time.

Are GB standard parts interchangeable with DIN parts?

For the common families — hex bolts, hex nuts, socket head cap screws, flat washers — yes, dimensionally. For cross-recessed screws, circlips and some specialised families, head geometry or groove dimensions can differ. Always check the mapping for the specific family before substituting.

Can I get samples before ordering production quantities?

Yes — this is the main use case for no-MOQ sourcing. Order the piece quantities you need for the prototype, verify fit and finish, then place the production order against the specification you confirmed. Keep the sample as the reference part.

What is the smallest size available?

In our stock catalogue, M0.8 is the smallest metric thread, with the deepest coverage from M1 to M3 in machine screws, socket head cap screws, nuts, washers and standoffs. Availability of individual part numbers varies; the catalogue shows live stock status per SKU.
