Type D Insert Nuts for Wood are self-tapping insert nuts that provide a strong and permanent thread for wood and wood-based sheet materials, and that are typically used for knock down furniture assemblies.
They are installed by simply screwing the self-tapping body into the base material.
The unique external thread of the Insert Nut Type D ensured positive locking and offers strong resistance against pull-out due to vibration, torsion or tensile loads. The flange head prevents the splitting of covered surfaces and driving the insert nut in too far.
The internal threads enable joint connector bolts to be secured for furniture assembly.
Available in sizes from M4 to M10 as standard – with special sizes, materials and finishes available to order.
