Workshop Warehouse Flat Washers ‘Form A’ – Metric M16 (HFW17)

Description

Genuine Workshop Warehouse · Part no. HFW17

Workshop Warehouse HFW17 are M16 flat washers, Form A to DIN 125, in heavy gauge zinc plated steel, sold as a workshop box (packed weight 1.02 kg). They go under the head or nut of an M16 bolt to spread the clamping load and protect the surface, a size for heavy brackets, trailer fixings and structural mounts.

Good to know

• Will these fit my bolt? They are for M16 bolts and studs; measure the bolt thread across its outside, about 16mm, before ordering, as an M16 washer on a smaller bolt will let it pull through off-centre.
• Form A or Form C? Form A is the standard flat washer; Form C (BS 4320) has a much larger outside diameter for soft or thin material, so choose that where the surface needs more support.
• Are they rustproof? Zinc plating gives light rust protection for dry and sheltered places; under a trailer or vehicle, expect some surface rust over time and treat it.

Which one?

For thin panels needing more spread, the Workshop Warehouse Flat Washers ‘Form C’ – Metric M8 (HFW61) show the wider Form C type; for smaller bolts, the Workshop Warehouse Flat Washers 'Form A' – Metric M8 (HFW14).
