Workshop Warehouse Repair Washers – Imperial 5/16 X 1 (M8 X 25) (HRW3)

Description

Genuine Workshop Warehouse · Part no. HRW3

Workshop Warehouse HRW3 are 5/16 x 1 repair washers, listed as the M8 x 25 equivalent: a 5/16in hole and 1in outside diameter in zinc plated steel. They are a good match for M8 fixings through thin sheet steel and plastic, such as heat shield brackets, battery trays, number plate plinths and exhaust hanger mounts.

Good to know

• Will they fit an M8 bolt? Yes; 5/16in is about 7.9mm, which an M8 bolt passes through with very little play, hence the M8 x 25 in the name.
• Can they fix a hole that has rusted out? Only if solid metal surrounds it; clean back the rust and treat the area first, because a washer over rotten metal just hides the problem.
• Which side of the panel should it go? Against the thin sheet or plastic, under whichever part turns as you tighten, so the bolt head or nut doesn't dig in and the hole doesn't stretch.

Which one?

For the same 5/16in hole with a wider face, the Workshop Warehouse Repair Washers – Imperial 5/16 X 1 1/2 (HRW4); for standard M8 washers, the Workshop Warehouse Flat Washers 'Form A' – Metric M8 (HFW14).
