Description
Overview:
This square plate washer is a heavy-duty, self-colour steel washer designed to spread the load of a fastener over a larger area and reduce the risk of surface damage or pull-through. It measures 4 inches (approximately 101.6mm) square and is 6mm thick, with a round M16 clearance hole suitable for standard M16 bolts, threaded rod, and anchor fixings. The uncoated (self-colour) finish is ideal where welding, priming, or painting is required, or where corrosion protection is managed elsewhere in the assembly. Commonly used across construction, civil engineering, plant maintenance, and machinery mounting, it provides a stable bearing surface on timber, steelwork, and concrete. Sold individually for flexibility, and referenced under MPN 903 1192, it offers reliable performance in site and workshop settings.
Key Features:
- 4" (101.6mm) square profile gives a large bearing area for effective load distribution
- 6mm thick plate resists bending under high clamping forces
- M16 hole suits standard M16 bolts, threaded rod, and anchor bolts
- Self-colour, uncoated steel: easy to weld, prime, or paint as needed
- Helps protect timber, steel, and concrete from fastener head or nut indentation
- Robust construction suitable for heavy-duty construction and machinery use
- Smooth, flat faces support even clamping and stable assemblies
- Sold individually to match project quantities and reduce waste
- Manufacturer Part Number (MPN): 903 1192
- Also available in hole sizes from M8 to M24 to match your fasteners
Typical Applications:
Used as a bearing plate under nuts or bolt heads for baseplates, anchor fixings in concrete pads, structural timber joints, machinery mounting feet, racking and mezzanine supports, fencing and gate posts, and agricultural or plant equipment repairs. Ideal wherever increased clamping area and reduced surface damage are needed.
