Description
Overview:
Metric Repair Washers M12 x 40mm are flat, wide-diameter washers used to spread the load under a bolt head or nut and protect the surface beneath. Manufactured from high-quality zinc‐plated steel, they offer reliable strength and good corrosion resistance for indoor and outdoor use. Each washer has a 12mm inner diameter to suit M12 threaded fasteners and a 40mm outer diameter for maximum bearing area. Built to BS 3410 dimensional standards, they provide consistent fit and performance in assemblies. Supplied in a pack of 100, they are well suited to routine maintenance, repairs, and new installs on construction equipment, garden machinery, fixtures, brackets, panels, and guards where softer materials or oversized holes need extra support.
Key Features:
- M12 sizing: 12mm inner diameter, 40mm outer diameter for wide load distribution
- Zinc-plated steel for durable corrosion resistance in varied weather conditions
- Conforms to BS 3410 for dependable dimensions and repeatable fit
- Large bearing surface helps prevent pull-through, crushing, and surface damage
- Ideal for covering oversized, slotted, or worn holes during repair work
- Works with bolts, set screws, studs, and nuts across many fastening tasks
- Smooth, flat faces provide stable clamping and even load transfer
- Suitable for construction and garden machinery assemblies and general fabrication
- Simple to install with standard hand tools; no special fittings required
- Pack of 100 supports site spares, service vans, and workshop stock control
Typical Applications:
Used wherever a larger bearing surface is needed: mounting brackets to frames, securing guards and panels, fixing components to timber, sheet metal, or plastics, and refurbishing holes that have enlarged over time. Common in machinery maintenance, plant repairs, fencing and decking fixes, equipment mounting plates, and general workshop fabrication where added support and stability are required.
Also known as:
Often referred to as penny washers, mudguard washers, large OD washers, spreader washers, and load‐spreading washers. These terms describe the same wide‐diameter flat washer style used to increase the contact area under fasteners and protect the mating surface during tightening.
