About this washer
This is a washer in Q235 Carbon Steel, supplied black oxide. 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 washer spreads the clamp load of the fastener over a wider area of the joint face and keeps the turning nut or head from scoring the part underneath. Fitted under bolts, screws and nuts on soft or painted surfaces, slotted holes, and any joint that is taken apart often enough for the face to matter.
Q235 is the standard Chinese structural carbon steel, roughly equivalent to S235JR / A36. Used for general-purpose bolts and anchors where a defined high strength grade is not required.
Black oxide is a conversion coating about 1–2 µm thick, usually oiled. It adds mild corrosion resistance and keeps dimensions exact, which matters on 10.9 and 12.9 parts — there is no hydrogen embrittlement risk.
Sold by the piece, so one is a valid order. Stock lines leave our warehouse within 24–48 hours of cleared payment, and freight is calculated at checkout from the packed weight and the destination.
