Allgrip 1/4 Inx3 Mudguard Washer M6 x 20mm, 4in, BZP, supplied in a pack of 200.
Mudguard washers have a large outside diameter that spreads the load over soft or thin materials such as sheet steel, timber or plastic. Used under bolt heads and nuts on trailers, bodywork and timber cladding where a standard washer would pull through.
Fit under both the head and the nut for the best spread.
