## Overview

The PowerCoil 3521-6.00K M6 x 0.75 Thread Repair Kit is designed to restore damaged threads or create new, robust ones. Made from precision profiled stainless steel wire, it offers a permanent, corrosion-resistant solution that outperforms original threads. Available in both free-running and thread-locking options, this kit is essential for any professional looking to ensure durability and reliability in their projects.

## Description

Product Description          Manufactured from high quality chromium nickel stainless steel, PowerCoil Wire Thread Inserts provide high strength internal threads that resist the effects of temperature and corrosion. Their unique design ensures superior threads whose compound performance cannot be reproduced by any other single fastening method. Available in two basic forms, free running or screw locking, they are much lighter and less expensive than any other equivalent type of thread insert and because of their compact size they can generally be incorporated into existing designs where no previous provision has been made. Free Running Produced from precision profiled austenitic stainless steel wire wound into a helical spiral, PowerCoil free running inserts have a spring like appearance. When installed, using any one of a variety of manual or automatic tools, they provide strong permanent internal threads which resist heat and corrosion. Once fitted, their position is maintained by the action of radial pressure between their coils and the flanks of the tapped hole. This pressure exists because their free diameter is larger by a calculated amount, than their installed diameter. Screw Locking 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 l ength, 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.

- PowerCoil wire thread inserts are manufactured from precision profiled diamond shaped stainless steel wire and formed into a helical spiral.
