About Leitech-US

Leitech - U.S.

  • Leitech-US is the exclusive Master Distributor for Leitech  Instruments of Gilleleje, Denmark — the inventors of the  simultaneous thread size and depth gage — serving the United  States, Canada, Mexico, and Puerto Rico since 1989. 


  •  We are a technical resource, not a catalog company. When you  contact Leitech-US, you reach someone who understands your  application, your thread standards, and your inspection  challenges. We help you find the right gage for your specific  part, process, and tolerance requirements. Our Milwaukee  facility handles certification, calibration, assembly,  repair, and shipping — everything you need, under one roof.  Have a custom thread size or special application? Our  engineering team will work with you to spec the right  gage — and get you a quote fast. 


  • Leitech Instruments was founded by Leif Larsen, whose insight  was simple and revolutionary: quality engineers shouldn't need  two tools to inspect one hole. That idea became the Leitech  COMBI Gage — and it changed how precision manufacturers approach thread depth inspection worldwide.
