Trilock gages are used to inspect large diameters. Like reversible gages, when one end wears out, the gage end can be turned around. This design significantly increases the gaging life of the gage. Gage members are securely attached to the trilock handle with mounting bolts. All Cylindrical Trilock plug gages are manufactured to ASME/ANSI B47.1 AGD standard and ASME/ANSI B89.1.5 standard. Gaging surface is hardened to Rc 60-62. Unilateral Tolerance Go – Plus Tolerance No Go – Minus Tolerance • Chrome Plated – Add 50% • Carbide gages priced on request • XXX Add 100% to XX prices up to 1.510" • Quantity discounts available on identical units • Larger diameters quoted on request • Certificate of Accuracy included • Long Form Calibration available at an additional charge
