About this item:
- M2.5 x 0.45 x 1.5D Screw Locking Insert
- Bulk Inserts Screw Locking M2.5 X 0.45 - 3.75
- PowerCoil Wire Thread Inserts strengthen tapped threads in light weight parent materials such as aluminium. They are helically wound inserts made from high quality chromium nickel stainless steel with a diamond shaped cross section.
- PowerCoil inserts are used in OEM applications in a wide range of industry sectors including aerospace, automotive, military and electronics.
- They are inexpensive when compared to other inserts and simple to install, yet are extremely tough, wear resistant and corrosion resistant.
- Most importantly, PowerCoil inserts allow the stress loading from the bolt or similar threaded part to be more evenly distributed over the threads in the parent material.
- Screw locking (or prevailing torque) inserts are of particular value in applications subject to the effects of cyclic vibration or impact.
- In addition to the benefits afforded by free running inserts, PowerCoil screw locking inserts offer the additional security of prevailing locking torque.
- This is achieved by the action of one or more polygonal grip coils positioned within the inserts 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 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.
