Description
Overview:
The Hardened Washer 12mm – often referenced as 100 124 – is a Non-Genuine replacement flat washer for use with M12 bolts and studs on construction plant and garden machinery. Made from heat-treated (through-hardened) carbon steel, it provides a tough bearing surface that resists indentation under high clamping loads. This helps maintain accurate torque, prevents bolt head or nut embedding, and protects painted or softer mounting faces. The internal diameter is 12 mm (approximately 15/32 in), making it suitable for standard M12 fasteners commonly found on compactors, mixers, generators, chippers, and ride-on mowers. A practical choice for routine maintenance and repairs, this washer supports reliable assemblies in brackets, guards, frames, engine mounts, and other critical fixings where durability and consistency matter.
Key Features:
- Non-Genuine replacement suitable for M12 fasteners (12 mm ID, approx. 15/32 in)
- Through-hardened steel resists embedding, fretting, and wear under high loads
- Helps maintain consistent clamping force and accurate torque settings
- Flat, smooth bearing faces for even load distribution and reduced surface damage
- Works with high-tensile bolt grades (e.g., 8.8, 10.9, 12.9) commonly used on machinery
- Simple drop-in replacement for worn or missing washers in many OEM assemblies
- Versatile use across construction, agricultural, and garden equipment
- Durable construction supports longer service intervals and reliable joint integrity
Typical Applications:
Used wherever M12 fixings are specified on machinery: chassis brackets, engine and gearbox mounts, vibration mounts, guard and cover fastenings, frame joints, tow or linkage points, and accessory installations. Ideal for compactors, cement mixers, generators, wood chippers, stump grinders, mowers, and similar equipment where a hardened bearing surface is needed to keep joints tight and components protected.
Also known as:
M12 hardened washer, high tensile washer, through-hardened flat washer, structural washer, M12 flat washer (hardened), heavy-duty washer for M12 bolts, load-spreading washer, plain washer M12 (hardened). These terms are commonly used in workshop manuals and parts lists for plant, agricultural, and garden machinery fixings.
