WEST BOYLSTON, MA U.S.A. (December 2, 2025) EMUGE-FRANKEN USA, a leading manufacturer of high-performance taps, thread mills, end mills, drills, gages, other rotary tools, and precision clamping solutions has announced the expansion of its SELF-LOCK™ Threading Tools Line with additional THREADS-ALL™ / AERO Thread Mills including fourteen new 2 x D sizes from #5-40 to 1″-12, and offered for the first time, thirty 3 x D sizes ranging from #2-56 to 1″-12. Also, the EMUGE High Ramp Precision Thread Gages Line for gaging EMUGE SELF-LOCK thread profiles has also been expanded.
EMUGE THREADS-ALL / AERO SELF-LOCK Thread Mills feature helical flutes, multiple teeth and TIALN-T46 coating, producing self-locking threads that are ideal in demanding industry applications such as aerospace where nickel alloys, titanium and stainless steel are the norm. A unique design enables three tooth pitches to simultaneously rough and finish-cut threads, dramatically increasing tool life and reducing cycle times.
“Offering a proven thread design that has been successfully working in thousands of safety critical applications, we are pleased to provide a substantially broadened line,” said Marlon Blandon, Thread Milling Product Manager, EMUGE-FRANKEN USA. “For high-stress situations, SELF-LOCK produces an internal thread that 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, eliminating slippage.
Other EMUGE SELF-LOCK products include UNC and UNF Cut Taps, UNC and UNF Form Taps; Metric Cut Taps, Metric Form Taps and Metric Thread Mills, in addition to a full line of GO/ NO-GO Thread Gages.
