Product Description
Metric Zinc Plated Steel Self Clinching Nuts – M3 to M8
Self clinching nuts provide a permanent internal thread in sheet metal, allowing matching machine screws or bolts to be fitted and removed during assembly and maintenance. These round steel press nuts have a zinc plated finish and are available in metric sizes from M3 to M8.
During installation, controlled squeezing pressure forces the surrounding sheet material into the nut's retaining feature. The serrated clinching section helps resist rotation once correctly installed.

Fitting Guidance
Select a clinching code suitable for the sheet thickness and check that the sheet material and hardness are compatible with the nut. Prepare the correct mounting hole and maintain the minimum distance from the hole centre to the sheet edge.
Install using suitable press tooling and a controlled, parallel squeezing action. Correct support and alignment are essential to achieve secure retention without distorting the panel.
