Description
Overview:
This square plate washer is a heavy-duty steel washer used to spread the clamping load of an M16 fastener and protect the surface beneath. The plate measures 3 inches (76.2 mm) square with a 3 mm thickness (approx. 0.12 inch), and features a round M16 clearance hole to suit M16 bolts, set screws, threaded rod, and anchors. The self-colour (plain) finish is practical for general construction, plant and machinery assembly, and site repairs, and can be painted or treated as required. The large, flat bearing face helps prevent pull-through and reduces indentation on softer or thinner materials. Suitable for use across construction fixings, agricultural equipment, garden machinery, site trailers, and workshop projects. Supplied individually for flexible, cost-effective replacements and new builds.
Key Features:
- 3 inch (76.2 mm) square plate with 3 mm thickness (approx. 0.12 inch) for a broad bearing area
- Round M16 clearance hole for use with M16 bolts, nuts, and threaded rod
- Distributes load to reduce surface damage, distortion, and pull-through on timber, sheet metal, and composites
- Self-colour steel finish: easy to prime, paint, or hot-dip galvanise if required by the application
- Flat faces for stable seating under bolt heads or nuts, improving joint integrity
- Robust plate design helps stabilise connections on uneven or oversized holes
- Versatile for construction, plant maintenance, fencing, racking, and machinery mounting points
- Sold individually to match exact repair or build quantities
Typical Applications:
Used under nuts or bolt heads on baseplates, brackets, machinery mounts, shuttering/formwork, fencing posts, site trailers, agricultural implements, and garden machinery. Ideal wherever a larger bearing surface is needed to protect timber, thin steel, or composite panels when tightening M16 fixings.
