West Boylston, Massachusetts – Emuge Corp.’s SELF-LOCK threading tools offer a high-quality alternative in thread locking for vital safety applications in aerospace, medical, communications, and transportation industries.

The Emuge thread locking feature is integrated in the internal thread and has a modified profile with a 30° ramp surface in the direction of stress which provides the self-locking effect. In an ideal screw connection for high-stress situations, where there is a standard external thread in an Emuge SELF-LOCK internal thread, the internal thread yields a self-locking screw connection that can be used repeatedly.

The profile of the SELF-LOCK thread allows an even distribution of stress over the entire thread length and therefore eliminates slippage.

Compared with standard threads, the Emuge SELF-LOCK internal thread shows constant, maximum holding power under dynamic stress. Functions remain in good operation even with repeated loosening and re-tightening of the thread connection. This locking effect is caused by the ramp-shaped surface integrated into the thread profile. 

SELF-LOCK technology offers increased threading tool life for larger thread hole diameters and provides larger tolerances for thread hole diameters. To gage SELF-LOCK threads, Emuge recommends using its two-piece gage system which corresponds to the usual combination of a go/no-go gage.

Emuge SELF-LOCK Threading Tools work with standard external threads (screws) in the medium tolerance class. Internal threads can be produced with Emuge taps, cold forming taps, or thread mills.
