About this DIN 25201 washer

This is a washer made to DIN 25201, in SK5 Spring Steel, supplied dacromet. 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.

Dacromet is a zinc-aluminium flake coating. It gives good corrosion resistance with no hydrogen embrittlement, which is why it is the recommended finish for grade 10.9 and 12.9 fasteners.

A spring steel: heat treated to stay elastic rather than rigid, which is what a spring washer or retaining ring needs.

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.
