  • Free Running Wire Thread Helical Inserts

    Produced from precision profiled austenitic stainless steel wire wound into a helical spiral, free running inserts have a spring like appearance. The damaged threads are drilled out with a specific sized drill bit and the hole is tapped with a special wire thread insert tap (NOT a standard size tap). 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. 

    The length shown in brackets (?mm) in the description is the length of the insert AFTER the insert has been installed. All metric inserts shown are standard coarse pitch, fine pitch threads are available for some diameters, please contact us for details.

    Please refine your search by selecting the diameter you require :-
