Description
Overview:
These Metric Serrated Flange Nuts are M8 fasteners made from steel with a durable zinc-plated finish for corrosion resistance. The integrated serrated flange spreads the load and bites into the mating surface to help prevent loosening from vibration, removing the need for a separate washer in many assemblies. They are widely used on construction equipment, plant, agricultural machinery, and garden tools, as well as general fabrication and maintenance. Suitable for use with standard hand spanners and sockets or power drivers, they provide a quick, tidy fastening where reliability and repeatability matter. Supplied in a cost-effective pack of 100 for workshop or site use. Manufacturer Part Number: 903 0682. A stainless steel variant is also available for harsher environments.
Key Features:
- M8 metric serrated flange design for improved grip and vibration resistance
- Zinc-plated steel for robust corrosion protection in indoor and outdoor use
- Integrated flange distributes load and reduces the need for separate washers
- Fast, neat installation with standard spanners or sockets
- Ideal for machinery assembly, guarding, brackets, and panel fixing
- Pack of 100 for bulk maintenance and production tasks
- Suitable for steel, aluminium, and painted brackets (note: serrations may mark surfaces)
- Helps maintain clamp load under vibration, reducing re-tightening
- Consistent quality for repeatable torque and seating
- MPN 903 0682 for straightforward identification and reordering
Typical Applications:
Commonly used in machinery assembly, plant maintenance, and fabrication. Suitable for securing engine covers, guards, brackets, frames, racking, fixings on compactors, generators, mowers, and other equipment subject to vibration. Useful on vehicles and trailers for bodywork and accessory mounting. Best used directly on the base material without a washer to allow the serrations to grip; avoid use on soft or delicate finishes where marking is a concern.
