Workshop Warehouse Flat Washers ‘Form A’ – Metric M8 (HFW14)

Description

Genuine Workshop Warehouse · Part no. HFW14

Workshop Warehouse HFW14 are M8 flat washers to DIN 125 Form A, made in heavy gauge zinc plated steel and packed as a workshop box weighing 0.94 kg. M8 is one of the commonest bolt sizes on a car, from brackets and heat shields to seat and battery mounts, so these see constant use on the bench.

Good to know

• What do they do under a nut? They spread the clamping force and give the nut a smooth face to turn on, so it doesn't bite into paint, plastic or a slotted bracket.
• Plain or spring washer? A flat washer spreads load but won't stop a nut working loose, and a plain spring washer does little more; a nyloc nut or threadlock resists vibration better.
• Will an M8 washer suit a 5/16in bolt? The sizes are close, about 7.9mm against 8mm, so it will usually go on, but for a snug fit match the washer to the bolt's own system.

Which one?

For bigger bolts, the Workshop Warehouse Flat Washers 'Form A' – Metric M16 (HFW17); for the same M8 size with a wider face, the Workshop Warehouse Flat Washers ‘Form C’ – Metric M8 (HFW61).
