Self Tapping Inserts have the added benefit of reducing wear within machinery which requires frequent clamping and unclamping. This amount includes seller specified domestic postage charges as well as applicable international postage, dispatch, and other fees. M4 steel threaded inserts enable you to install a threaded hole in to wooden and composite materials. Our screw locking inserts have all of the advantages of a free running type plus the additional benefit of prevailing locking torque, which makes them a valuable and reliable choice for use in applications subject to cyclic vibration or impact. The locking torque is achieved by the action of a polygonal grip coil in the insert that exerts radial pressure on the male thread, with each grip coil consisting of a number of tangential locking chords that protrude inside the minor diameter of the normal free running coils.

As the male thread passes through these grip coils, the locking flats are displaced, thereby exerting radial pressure and prevailing locking torque on the male thread. Note: It is recommended that only close fit plated or lubricated bolts and screws are used with screw locking inserts. Our standard free running wire thread inserts are produced from Austenitic Stainless Steel wire (304/A2 Stainless), which is cold drawn (profiled) to form a diamond-shaped wire.
