Effort-saving" Self-Tapping Insert "Enzart

Effort-saving" Self-Tapping Insert "Enzart

No troublesome pre-tapping required! Easy installation in just 3 steps for anyone!

The insert nut is a work-friendly insert that can be used in materials such as resin and aluminum, which are prone to thread damage when directly tapped. It is used to reinforce the threaded sections of materials with low mechanical strength. Since the external threads of the insert nut support the axial force of the screw, it can extract more strength from the material than a directly tapped screw. The reinforcement using the insert is limited by the shear strength of the specific material or the mechanical strength of the bolts used, but the insert itself does not break.
