About this washer
This is a washer, with an M3.5 thread. 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.
M3.5 is a metric thread with an 3.5 mm nominal diameter and a coarse pitch of 0.6 mm (ISO 261). A standard hex head takes a 6 mm spanner across the flats.
This line ships worldwide from our own warehouse. Express courier, air parcel and postal services are all offered at checkout, with a tracking number e-mailed as soon as the parcel is handed over.
