Who We Serve

Any Industry. Any Thread. System Leitech.

Every industry that machines metal parts with threaded features shares one challenge: the thread  has to be the right size and the right depth —  or the assembly fails.  


Leitech COMBI Gages solve that problem with one  tool, one operation, and one direct numerical  reading. From turbine engines to titanium implants,  from transmission housings to hydraulic manifolds,  from diesel engine blocks to bone screws — the  physics are the same. So is the solution.  If it's a precision hole in a machined metal part  — Leitech measures it.
