Description

Overview:
This Square Plate Washer with an M12 hole is a sturdy steel washer for spreading load under nuts and bolt heads on structures and machines. The square plate format offers a larger bearing area than standard round washers, helping to prevent pull-through and surface damage on timber, steelwork, and concrete fixings. It measures 3 inches (76.2 mm) across and is 3 mm thick, with a round hole sized for M12 bolts and threaded rod. The self-colour (plain) finish suits indoor use or locations where it will be painted or galvanised after fitting. Sold individually, it is a practical choice for tasks from machinery mounting to site joinery and formwork, and works with common M12 fixings used on tools, plant, and building hardware.

Key Features:
- Square plate design provides a wide bearing surface for better load distribution
- 3 inch (76.2 mm) square, 3 mm thick plate for medium-duty applications
- M12 round hole to suit standard M12 bolts, studs, and anchors
- Steel construction for strength and reliability under clamping loads
- Self-colour finish ready for painting or separate corrosion protection if required
- Helps prevent indentation and damage on timber, sheet metal, and base plates
- Easy to fit with standard hand tools; no special tooling needed
- Sold individually to match the exact quantity needed on site
- Useful as a spacer or shim to align components and level assemblies
- Compatible with through-bolts, anchor bolts, and machinery mounting fasteners

Typical Applications:
Load-spreading under M12 fixings on timber frames, fencing, decking, and formwork; mounting machinery and equipment to skids or base plates; bracing steel fabrications; securing anchor bolts in concrete; general maintenance as a spacer or shim to achieve alignment and protect surfaces from clamp pressure.

Also known as:
Square washer, spreader plate, anchor washer, packing plate, load spreader, base plate washer, timber washer, plate shim, square flat washer.
