Spiralok Tangless Inserts and Tools

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. Crest of bolt seats against ramp of Spiralock® insert thread profile, preventing transverse movement of bolt relative to insert, thus resisting loosening due to vibration.
