Description
Overview:
These heavy-duty stainless steel flat washers have a precise inner diameter (I.D.) of 20 mm and come in a pack of 50 for workshop and site use. Made from corrosion‐resistant stainless steel, they spread the clamping force of nuts, bolts, set screws, and studs to protect surfaces and maintain joint integrity. The 20 mm I.D. typically suits M20 fixings, providing a stable bearing surface on metalwork, timber, and plastics. Ideal for construction equipment, plant, garden machinery, and general fabrication, they help prevent damage, reduce wear, and improve long-term reliability in bolted assemblies on items such as mowers, generators, pumps, compactors, trailers, guards, and brackets. A practical stock item for both tradespeople and DIY users where durable, weather‐resistant fixings are required.
Key Features:
- Heavy-duty stainless steel construction for strength and corrosion resistance in outdoor and indoor environments
- 20 mm inner diameter for use with M20 fasteners and threaded rod where applicable
- Flat profile provides a wide, smooth bearing surface to spread load and protect substrates
- Helps reduce surface crushing, fretting, and loosening caused by embedment under bolt heads and nuts
- Suitable for use with nuts, bolts, set screws, and studs across machinery and structural fixings
- Consistent sizing for repeatable assembly and reliable clamp force
- Pack of 50 for maintenance, repairs, and small production runs
- Useful on painted, plated, timber, plastic, and softer materials to minimise damage
- Weather-resistant material supports long service life in harsh site conditions
- Part of a wider size range from 3 mm to 24 mm to cover varied applications
- Manufacturer Part Number (MPN): 903 0968 for easy identification and reordering
Typical Applications:
General machinery assembly, bracket and guard mounting, chassis and frame fixings, fencing and gate hardware, timber-to-steel connections, and repairs on garden and construction equipment. Common on mowers, generators, pumps, compactors, and trailers where load spreading and surface protection are needed. Suitable for maintenance, installations, and fabrication work in workshops and on site.
Also known as:
Plain washers, flat washers, load-spreading washers, spacer washers, shim washers, packing washers, and sometimes referred to as gaskets in informal use. These terms describe flat discs used under bolt heads or nuts to distribute load and protect mating surfaces.
