Description
Overview:
The Square Plate Washer, M10, is a heavy-duty washer used to spread the load of a fixing and protect the mating surface. Made from mild steel in a self-colour finish, it measures 3 inches (76.2 mm) square and 3 mm thick, with a central round hole for M10 bolts or threaded rod. The large square profile helps prevent pull-through on softer materials and thin sections, improving joint stability in construction, agricultural, and garden machinery assemblies. It is suitable for mounting brackets, machinery guards, base plates, and structural fixings where a wider bearing area is needed. This listing is for the M10 size and is sold individually, allowing you to buy the exact quantity required.
Key Features:
- 3 inch (76.2 mm) square plate gives a wide bearing area to reduce surface damage
- 3 mm thick mild steel for solid, long-lasting support under clamping loads
- M10 clearance hole sized for standard M10 bolts and threaded rod
- Self-colour steel can be painted, primed, or coated for corrosion protection as required
- Helps prevent bolt heads and nuts pulling into timber, sheet metal, or composite panels
- Improves load distribution for more secure assemblies on machinery and structures
- Simple to fit with standard hand tools; no special fittings needed
- Flat profile sits neatly under nuts, bolt heads, and structural plates
- Suitable for through-bolting, anchoring, and repair work on site or in the workshop
- Sold individually for precise quantity control and minimal waste
Typical Applications:
Spreading bolt loads on timber frames, fence posts, shuttering, and joinery; reinforcing fixings on plant and garden machinery guards; anchoring base plates to concrete with through-bolts; securing brackets, winches, and hoists; repairing enlarged or worn holes; mounting equipment to vehicle bodies, trailers, or site cabins; general fabrication where a larger bearing surface is needed.
