Spiralock® Wire Inserts

Spiralock^® wire thread inserts are helically coiled fastening devices that provide permanent, wear-resistant screw threads that exceed the strength of most parent material; the inserts are designed to protect tapped holes against failures due to stripping, seizing, corrosion, and wear.

Spiralock^® inserts are unlike any other wire thread insert for the fact that our inner diameter wire geometry incorporates our 30° wedge ramp thread form design. Our wire thread inserts are available in two styles: tanged and Drive Notch, engineered with no tang.
