Our standard free running wire thread inserts are produced from Austenitic Stainless Steel wire, which is cold drawn (profiled) to form a diamond-shaped wire. This wire is then helically coiled to produce the wire thread insert.
Larger in diameter than the tapped hole, the insert is compressed during installation to ensure maximum surface contact between the flanks of the wire insert and tapped threads. Once fitted, the action of the radial pressure between the insert's coils and flanks of the tapped hole holds them in place securely.
The flexibility of our inserts enhances load bearing capacity by deflecting the residual forces into a helical direction, which is dispersed into the wall of the tapped hole.
Sometimes referred to by the brand names of Helicoil® or Recoil®, helically-coiled wire thread inserts are a thread strengthening fastening device used to create high strength fastenings in softer core materials. The high performance internal thread provided by our wire inserts is far stronger than most parent materials, and is also heat, corrosion, and wear resistant too.
Manufactured wire inserts in free running and screw locking types in a huge range of sizes and lengths in Metric, Unified, and British Standard thread forms. Made from aircraft quality 304/A2 stainless steel wire, we can also offer stock and supply inserts in a range of alternative materials and finishes, each of which have their own unique benefits. We can also apply colouring to inserts too, which is often requested by customers for identification purposes.
