Description
Overview:
The Metric Serrated Flange Nuts, Zinc Plated, Size: M6, are all‐metal fastening nuts designed to hold joints securely in applications where vibration is common. Made from steel with a bright zinc‐plated finish, they offer dependable corrosion resistance for indoor and outdoor use. The integral serrated flange spreads the clamping load and bites into the mating surface to resist loosening without a separate washer. These M6 nuts pair with matching M6 bolts or threaded studs on construction equipment, garden machinery, frames, brackets and housings. Supplied in a pack of 100 for efficient restocking on site or in the workshop. Stainless steel variants may also be available if you need extra corrosion protection for harsher environments or frequent wet use.
Key Features:
- M6 metric thread for broad compatibility with common machinery fasteners
- Serrated flange provides a locking action that helps prevent loosening under vibration
- Integrated washer face spreads load and reduces the need for separate washers in many assemblies
- Zinc‐plated steel for reliable corrosion resistance and a clean, durable finish
- Speeds assembly: fewer parts to handle and align during fitting
- Suitable for use with standard spanners or sockets; torque setting can be applied where required
- Ideal for metal‐to‐metal joints on frames, guards, brackets and engine covers
- Pack of 100 for maintenance teams, installers and regular workshop use
- Helps maintain joint integrity on equipment subject to shock, vibration or cyclic loading
- Commonly used as a practical alternative to thread‐locking compounds in routine assemblies
Typical Applications:
Securing panels, guards, brackets, vibration mounts and engine covers on compactors, generators, lawn mowers, strimmers, pumps and workshop fixtures. Useful for racking, trailers, agricultural implements, fencing hardware and general fabrication where joints are exposed to movement. Best suited to metal substrates; the serrations may mark painted or soft surfaces.
Also known as:
Hex flange lock nuts, locking flange nuts, toothed flange nuts, serrated face nuts, washer‐faced lock nuts, M6 flange lockings, M6 hex lock nuts, flanged locking nuts.
