Spring Washers

7 products

Rectangular-section spring washers to DIN 127-B in A2 (304) and A4 (316) stainless steel - single-coil compression washers that sit under the nut and resist vibration loosening in bolted joints.

Uses include machine mounts, engineering assemblies, garden furniture, kit builds and any joint where a nyloc nut is unavailable or overkill. M4 through M8 sizes across A2 and A4 grade. Stack directly under the nut on top of a Form A flat washer for the classic bolted-joint sandwich. DIY and Trade packs available, free next-day UK delivery on orders over £50.
