High Strength Hexsert 39301 Series


M6, M8, M10, M12

Head Style:

Large Flange

High strength Hexserts provide clamp force comparable to weld nuts and clinch nuts in high torque applications. They offer equivalent thread proof load strength to ISO 898 Property Class 10 weld nuts and clinch nuts, and can handle tightening torques commonly applied to Property Class 10.9 and 12.9 screws and bolts.


Increased thread strength

Exceptional torque capability

If excessive torque is applied, the screw shank should fail before the insert, avoiding over-tightening problems such as thread stripping and expensive rework

Provides high-strength threads in thin materials starting at 0.5mm
