Description
Overview:
Metric Serrated Flange Nuts in M5 size, supplied in a pack of 100, made from zinc-plated steel for strength and dependable corrosion resistance. The integral flange spreads the load like a built-in washer, while the serrations bite into the mating surface to help resist loosening from vibration. This makes them a practical choice for assemblies on construction and garden machinery such as lawn mowers, compactors, cement mixers and generators. The hex profile allows easy tightening with standard spanners or sockets. Suitable for indoor and outdoor use where a secure, long-lasting joint is required. Common reference: MPN 903 0680. Standard M5 coarse thread (0.8 mm pitch) fits matching M5 bolts and studs used across brackets, guards, frames and engine-mounted components.
Key Features:
- M5 coarse thread (0.8 mm pitch) for wide compatibility with common bolts and studs
- Serrated flange provides anti-vibration resistance and reduces the need for a separate washer
- Zinc-plated steel for durable, rust-resistant performance in general outdoor environments
- Hex drive for quick fitting and removal with standard hand tools and sockets
- Flanged face spreads clamping force to reduce surface damage and improve joint stability
- Reliable grip helps maintain preload on machinery subject to shock and vibration
- Supplied in a pack of 100 for routine maintenance, repairs and bulk use
- Silver zinc finish gives clear visibility during assembly and inspection
Typical Applications:
Used to secure guards, brackets, panels, covers and fixtures on equipment exposed to vibration, including lawn mowers, hedge trimmers' attachments, plate compactors, cement mixers, pressure washers, small generators and trailers. Suitable for fixing control boxes, engine cowls, exhaust shields, and frame connections. Ideal for metal-to-metal joints where a firm, locking action is needed without adding a separate washer.
