Product Description

WTI Screw-Locking wire Helical Insert

For applications subject to cyclic vibration or impact, screw locking inserts are of particular value. WTI screw locking inserts offer the security of prevailing locking torque in addition to the benefits delivered by free running inserts.

This is achieved by the action of one or more polygonal grip coils positioned within the insert's length, which exert radial pressure on the male thread. Each grip coil consists of a number of tangential locking chords which 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, thus exerting radial pressure or prevailing locking torque on the male thread. On removal of the male thread, the locking coils relax to their original form permitting repeated assembly whilst retaining a measurable level of prevailing torque. Note: it is recommended that only close fit plated or lubricated bolts or screws are used with screw locking inserts.
