V-Coil 3 mm Wire Thread Repair Inserts for M3.0 x 0.5 1.5D 20 off

1.5D inserts installed length 4.5mm

 

Produced from precision profiled austenitic stainless steel wire wound into a helical spiral, 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.

Inserts are 1.5D installed length this means 1.5 x diameter. Other installed length are available please email if this is your requirement and we can list on ebay for you.

Inserts are priced and supplied in packs of 20
