Description
Overview:
This square plate washer is a heavy-duty load-spreading washer for M20 fixings, made from plain (self‐colour) steel for strength and reliability. It measures 3 inches (approximately 76 mm) square and 3 mm thick, providing a broad bearing surface under a nut, bolt head, or anchor to reduce the risk of pull‐through and damage to the workpiece. It is suitable for construction, plant and agricultural machinery, site equipment, steel fabrication, and timber structures where a robust, low‐profile washer is required. The self‐colour finish is ideal where you plan to prime and paint on site. Suits M20 bolts and threaded rod in general assemblies and anchor fixings. Sold individually for accurate quantity control. Manufacturer Part Number (MPN): 903 1190. Matching washers are commonly available across M8 to M24 hole sizes to cover related tasks.
Key Features:
- 3 inch (76 mm) square profile spreads load over a wider area for better protection of steel and timber substrates
- M20 hole suits M20 bolts, nuts and threaded rod for structural and machinery fixings
- 3 mm thick steel provides a sturdy, low‐profile bearing surface without excessive build height
- Plain (self‐colour) steel finish: easy to prime and paint for corrosion protection if required
- Helps prevent surface bruising, distortion and fastener pull‐through in softer or thin materials
- Simple to fit: place between the fastener and the surface for immediate load distribution
- Consistent dimensions support repeatable assembly and reliable clamp loads
- Suitable for use with anchor bolts, base plates, brackets, machinery mounts and frame connections
- Sold individually to match project quantities and reduce waste
- Complements a wider range typically spanning M8 to M24 for site standardisation
Typical Applications:
Used under nuts or bolt heads on base plates, brackets and machinery feet; for anchoring to concrete with threaded rod; strengthening fixings in timber frames and fencing; clamping sheet metal or channel sections; and general plant maintenance where a wider bearing area is needed to protect the substrate and maintain clamp force.
