Helical Coil Thread Plug Gages - 5/8-18 - Inch - Steel - GO / NOGO - X
Helical coil (STI) work plug gages are used to gage threaded holes prior to the insertion of the screw thread insert (STI) and are typically taperlock design. Screw thread inserts are used to repair a damaged thread or provide a stronger threaded assembly and are widely used in the automotive industry.
Taperlock thread plug gages are available with GO and/or NOGO plug members and are manufactured to Class X tolerance in 2B or 3B. All gages are inspected in an environmentally controlled lab and manufactured in full conformance to ASME/ANSI B1. 2 WESTport helical work plug gages are manufactured to the highest end of the ANSI specifications to ensure the longest gage life possible. Available in steel.
WESTport Gage manufactures special plug and ring gages including oversize pre-plates, miniature thread gages, multiple starts, special leads, acme threads, buttress threads, square threads, extra length thread gages, and blue print specials. WESTport Gage provides a Certificate of Accuracy, traceable to NIST (National Institute of Standards and Technology), free of charge with every helical coil (STI) thread plug gage.
