Insert Nuts For Wood Type I have external teeth or barbs which provides a strong, permanent thread for wood and wood based materials, providing substantial holding power even when torqued laterally. The coarse external tooth (barbed) pattern ensures maximum holding power and simplified installation by knocking the Insert into the base material.

The Type 1 insert nut has a blind (closed) round surface flange which is pressed / hammered into position through the pre drilled pilot hole. Once in position the ‘Joint Connector Bolt‘ can be inserted from the adjacent side and screwed into position, mating with the insert nut tp provide a strong clamping force, increasing its holding power and producing an aesthetically pleasing finished appearance.
