Description
Overview:
The Metric Serrated Flange Nuts, Size M12, are durable steel fasteners with a bright zinc-plated finish for corrosion resistance. The integral serrated flange acts like a built-in washer, spreading the clamping load and helping to resist loosening caused by vibration. This makes them a solid choice for construction equipment, agricultural implements, workshop fixtures, and garden machinery. Their standard hex form fits common spanners and sockets, making installation straightforward in through-hole or threaded hole assemblies. Supplied in a pack of 50, they are suitable for stocking in site kits and maintenance stores for routine repairs and assembly work. Commonly paired with M12 bolts and studs for frames, brackets, guards, engine ancillaries, and panels. Manufacturer reference for identification: 903 0684.
Key Features:
- M12 metric thread size for widespread compatibility in machinery and plant maintenance
- Serrated flange provides a positive locking effect under vibration, often removing the need for a separate washer
- Steel construction with zinc plating for dependable corrosion protection in indoor and outdoor use
- Hex drive for quick fitting and removal using standard spanners or sockets
- Wide bearing flange helps distribute load and protect mating surfaces
- Consistent thread quality for smooth assembly and predictable torque
- Supplied in a practical pack of 50 to cover builds, refits, and spares
- Neutral silver BZP finish to match common fastener sets
- Suitable for metal-to-metal joints where a firm, vibration-resistant clamp is required
- Manufacturer reference: 903 0684 for easy reordering
Typical Applications:
Securing brackets, guards, covers, engine mounts, housings, and fixtures on construction plant, agricultural equipment, trailers, and garden machinery. Useful on vibrating equipment such as compactors, generators, compressors, cultivators, and ride-on mowers. Suitable for assembly lines, site repairs, workshop maintenance, and upgrade projects where reliable, vibration-resistant fastening is needed.
