About this fastener

This is a fastener in 65Mn Spring Steel, at strength class Grade 4.8, supplied blue-white zinc plated. Every dimension is stated against the standard named above; where a tolerance class matters to your design, ask us and we will confirm it in writing before you order.

A fastener from our catalogue, held in stock in the material and grade shown on this page. Used for general engineering, maintenance and assembly work, and available in single pieces as well as full cartons.

Blue-white zinc plating is a bright electroplated finish with a slight blue passivate tint, typically 5–12 µm. Suits indoor and sheltered assemblies.

65Mn is a manganese spring steel used for spring washers, retaining rings and clips, where the part must stay elastic rather than rigid.

There is no minimum order and no free-shipping threshold: buy one piece or a full container. Your order total is confirmed in the cart, before payment.

Stock items are picked and dispatched within 24–48 hours from our Foshan warehouse. We ship worldwide by express courier (DHL, FedEx, UPS), air parcel or postal ePacket — you choose the trade-off between cost and speed at checkout. Tracking is provided for every shipment.

If a line arrives with a dimensional or material fault, send photographs and the batch number — we replace it or credit it in full and cover the return freight when the fault is ours. Fasteners are supplied to specification and sold by the piece, so we do not run a general change-of-mind return window, and anything made to your drawing is final sale unless it fails the agreed specification.

We supply 304/316 stainless and grade 8.8/12.9 steel. EN 10204 3.1 mill test certificates are available on request for trade orders. Batch numbers are printed on every carton label.
