Description
Overview:
This Square Plate Washer is a heavy‐duty steel washer with a central M20 (20 mm) hole, designed to spread clamping loads and protect mating surfaces in structural fixings and machinery installs. Made from plain (self colour) steel, it offers a robust, versatile bearing surface that reduces pull‐through and damage to timber, steel, or concrete. The square footprint measures 3 inches (76 mm) and the plate is 6 mm thick for dependable rigidity under high tightening forces. Ideal for use with M20 bolts, threaded rod and anchor bolts on plant, construction frames, machinery bases and agricultural equipment. Sold individually for one‐off repairs or project quantities, with wider range options typically available from M8 to M24. Manufacturer Part Number (MPN): 903 1193.
Key Features:
- Heavy‐duty steel construction with self colour (plain, uncoated) finish for straightforward painting or post‐fabrication treatment
- 3" (76 mm) square footprint provides broad load distribution and reduces surface indentation
- 20 mm clearance hole suits M20 bolts, studs, threaded rod and anchor fixings
- 6 mm plate thickness resists cupping and pull‐through under high torque
- Smooth, flat faces help protect timber, steel and concrete substrates
- Simple to fit under the nut or bolt head; no special tools required
- Reliable choice for structural connections, baseplates and hold‐down details
- Sold individually to minimise waste on repairs and small jobs; pack options commonly available for larger works
- Part of a wider washer range covering common fastener sizes (M8-M24)
- Suitable for indoor or outdoor use when appropriate corrosion protection is applied
Typical Applications:
Load‐spreading washer for M20 fasteners in timber frames, sole plates, formwork, fencing and post bases. Common on machinery base fixings, anchor bolts for generators and compressors, steelwork connections, agricultural implements and trailers, and general construction where a larger bearing area is needed to protect surfaces and improve joint stability.
