⚡ At a Glance
- • Holding Strength: Serrated flange bites into the mating surface to resist rotational loosening under vibration
- • Best for: DIY enthusiasts, builders and maintenance professionals needing reliable metric M8 fastenings
- • Not ideal for: Applications needing a smooth bearing surface or frequent repositioning where marks are unacceptable
Metric M8 serrated flange hex nuts in zinc plated steel. Serrated flange helps prevent loosening under vibration.
Secure connections - thanks to serrated flange
Raised serrations on the flange press into the mating surface and create friction, reducing rotational movement when assemblies vibrate. The hex profile provides standard engagement for spanners and sockets.
Fastenings stay tight in vehicle mounts, machinery brackets and fixtures exposed to movement, cutting down frequent retightening.
Corrosion resistance - with zinc plated steel
A zinc plating layer covers the steel substrate to slow oxidation and surface rust in normal environments. The finish is suitable for indoor and sheltered outdoor conditions.
Suitable for general building and maintenance tasks where basic rust protection is required, extending service life compared with raw steel.
Standard compatibility - with DIN 6923 metric specification
Manufactured to DIN 6923 standards for serrated flange nuts, ensuring consistent flange dimensions and thread compatibility for M8 fasteners. Metric sizing aligns with common M8 bolts and threaded rods.
Simple to source matching bolts and replacement fasteners, and straightforward to fit with common tools used on-site.
