Product Description

Trilock Cylindrical plug gages are used to check a drilled hole. When one end of the gage becomes worn or damaged, the gage member can be reversed providing exceptional value, essentially two gage members for the price of one. The trilock feature is the source for the name of this design. The handle has three prongs on the ends, which fit into three grooves equally spaced around the central hole of the gage members. A bolt fastening system holds the member to the handle and the trilock grooves and prongs stabilize the member.

This gage is designed for size ranges, .750” to 8.00”. Available with GO and NOGO members in Class XXX, XX, X, Y and Z and manufactured to American Gage Design standards (AGD). Double end gages are supplied with (+) plus tolerance on the Go member and (-) minus tolerance on the NOGO member. Aavailable in steel, chrome and carbide. Steel gages are made of premium 52100 tool steel hardened to Rockwell C62-64 and cold stabilized to minimum size and form variations throughout providing the user with longer gage life and maximum wearability.

Special features such as depth notches, special lengths, air flats, easy entry pilots, whistle notches, radius, and chamfers are priced on request. WESTport Gage provides a Certificate of Accuracy, traceable to NIST (National Institute of Standards and Technology), free of charge with every gage.
