Description
Overview:
Form A Flat Washers with a 6 mm inner diameter are zinc-plated steel washers designed for everyday fastening on construction and garden machinery. They spread the load beneath bolt or screw heads and nuts, protect painted or softer surfaces, and help maintain stable clamping force. Made to BS4320 Form A, they offer consistent fit and repeatable assembly on M6 fasteners. Each washer has a 6 mm (0.24 in) I.D. and a 12 mm (0.47 in) O.D., with a bright zinc finish for corrosion resistance in outdoor and workshop conditions. Suitable for equipment such as lawn mowers, generators, plate compactors and cultivators, this pack of 500 supports assembly, repair, and routine maintenance where reliable, even load distribution is required.
Key Features:
- BS4320 Form A dimensions for a predictable, consistent fit
- 6 mm (0.24 in) inner diameter to suit M6 bolts, screws and studs
- 12 mm (0.47 in) outer diameter to spread load and reduce surface marking
- Zinc-plated steel for enhanced corrosion resistance in damp or outdoor use
- Smooth bearing surface supports consistent tightening torque
- Bright finish aids quick identification during assembly and maintenance
- Supplied in a bulk pack of 500 for workshop stock and site spares
- Simple to fit and replace using standard hand or power tools
- Suitable with steel, aluminium, timber and plastic components
- Useful in slotted holes to minimise pull-through and edge damage
Typical Applications:
Common on machinery panels, guards, brackets and control boxes; under nuts and bolt heads on lawn mowers, generators, compactors and small plant; fixing sheet metal, frames and enclosures; assembling racking, jigs and fixtures; distributing load on timber gates, sheds and decking; and general repairs where preventing surface damage and maintaining clamp force on M6 fasteners is important.
Also known as:
M6 flat washers, steel washers, zinc-plated washers, load-spreading washers, spacing washers, spacers, shims, M6 washers.
