Description
Overview:
The Square Plate Washer with M10 hole is a heavy-duty washer for spreading clamping loads and protecting surfaces in construction, plant, and machinery fixings. Made from plain (self colour) steel and supplied as a square plate measuring 1.1/2 inches (38 mm) across and 3 mm thick, it provides a larger bearing area than standard round washers. This helps prevent pull-through and reduces damage on timber, steelwork, and masonry when used with suitable anchors. It fits M10 bolts, set screws, coach bolts, and threaded rod in common site and workshop assemblies. Sold individually so you can buy the exact quantity required. This M10 version is part of a wider range available in hole sizes from M8 to M24 for consistency across a project.
Key Features:
- M10 clearance hole for use with M10 bolts, coach bolts, and threaded rod
- Square plate size: 1.1/2 inches (38 mm) for increased load spread compared with standard washers
- 3 mm thick steel helps resist cupping and deformation under clamping force
- Self colour finish: suitable for priming, painting, or galvanising; apply protection where corrosion resistance is required
- Smooth edges for stable seating under bolt heads and nuts
- Helps protect timber, steel plate, and concrete surfaces from localised pressure
- Ideal for base plates, bracketry, machinery feet, and structural fixings
- Easy to fit: place under the nut or bolt head to distribute load evenly
- Sold individually for flexible quantities on site or in the workshop
- Part of a versatile range with hole sizes from M8 to M24 for matched installations
Typical Applications:
Load-spreading washer for anchoring base plates, machinery mounts, timber-to-steel connections, formwork bracing, guardrails, posts, racking, and frames. Common in building, civil engineering, fencing, agricultural equipment, garden machinery mounts, and general fabrication where a wider bearing area is needed around an M10 fixing.
