Emuge Corp., a leading manufacturer of high-performance taps, drills, end mills, and other rotary tools, has announced its industry-leading thread making tool quality is available in a Self-Lock integrated locking system. Emuge Self-Lock threading tools offer a high-quality alternative in thread locking for vital safety applications in aerospace, medical, communications, transportation industries, and more.
The Emuge thread locking feature is integrated in the internal thread and has a modified profile with a 30-degree 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 special profile of the Self-Lock thread allows an even distribution of stress over the entire thread length and therefore eliminates slippage,”said Mark Hatch, product director at Emuge Corp. “We are pleased to offer such a safety critical threading solution which results in no stripping of threads and is cost-effective because no additional components are necessary.”
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 results in increased threading tool life for larger thread hole diameters and provides larger tolerances for thread hole diameters. Also, assembly is easy with no assembly errors possible — such as forgetting the locking device. 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) with tolerance class “medium.” Internal threads can be produced with Emuge taps, cold forming taps or thread mills.
