Wood Insert D-Nut

Product Description

A nut insert is a type of fastener that is fitted into the back side of material, such as wood, because the material cannot itself be tapped for machine threads. A wood insert nut is a hollow metal cylinder with internal threads that match the thread size and pitch of the machine bolt it is intended to be used with. Insert nuts for wood may have a coarse outer thread that turns into a matching tapped thread in the wood

These Type D Insert Nuts provide a strong, permanent thread for wood and wood-based sheet materials. The incorporated flange alleviates splitting and prevents the Insert Nut from being driven in too far.

To install, simply screw the self-tapping body into the base material. The unique external thread ensures secure fixing and offers strong resistance to pull-out due to torsion or vibration.

Typical applications include audio equipment, cabinets, chairs, desks and shop equipment.


Insert nuts for wood type D are available from stock in zinc alloy from M3 to M10 in various lengths and finishes (usually zinc or zinc & yellow).
