⚡ At a Glance
- • Holding Strength: Robust thread contact for secure clamping under moderate loads
- • Best for: DIY enthusiasts, maintenance crews and small assembly tasks
- • Not ideal for: Environments requiring stainless-steel corrosion resistance or very high temperatures
M8 hexagon domed cap nuts made to DIN 1587 dimensions with a 1.25mm thread pitch. Black zinc flake finish gives added surface corrosion protection and a discreet appearance.
Secure thread engagement - with M8 size and 1.25mm pitch
Threads match standard M8 bolts with a 1.25mm pitch, and a nut height of 14.6mm allows multiple thread turns. DIN 1587 designation ensures consistent dimensional tolerances for compatible fastenings.
Reliable mating with M8 bolts reduces loosening under vibration and keeps assemblies tightly clamped. Suitable for typical mechanical joints in furniture, brackets and light machinery.
Improved corrosion resistance - with Black Zinc Flake finish
Black zinc flake is a surface coating applied to the nut exterior to form a protective layer over the base metal. The finish is low-reflective and helps limit surface oxidation in ordinary indoor and sheltered outdoor conditions.
Fittings remain presentable for longer, especially in exposed or damp indoor locations. Regular maintenance still recommended for harsher conditions.
Neat, protective appearance - with domed cap design (DIN 1587)
Domed cap geometry encloses the protruding bolt end, consistent with DIN 1587 dimensional form. The cap reduces the chance of snagging and shields the thread tip from direct contact.
Finished assemblies look cleaner and are safer to handle, with fewer exposed threads catching clothing or causing scratches. Ideal for visible installations and trim work.
