Cap Nuts Black

We offer black cap nuts in the sizes M6 and M8. Cap nuts provide your work with a clean finish and protect you against sharp edges of the bolt. This significantly decreases the change of something getting hooked on the bolt or someone injuring themselves. Essentially, cap nuts are hex nuts that are closed on one side. 

These cap nut have a unique High Corrosion Protection coating (HCP-coating), a treatment providing the cap nut with its black colour as well as protection against corrosion. Salt spray tests show that this treatment causes the cap nut to have a corrosion-resistance of over 500 hours.
