Standard Plug Gages
Alameda Thread Gages are manufactured per ANSI/ASME B1.2 and B1.16M, and are stocked in class X tolerance. We offer UNC, UNF and UNEF inch gages in class 1B, 2B, 3B, and 6H in metric. For UNJ and MJ, add $10 to plug price. Standard plug gages are offered in taperlock, trilock and reversible styles. Taperlock gages are popular due to their convenience of replacing members. Trilock handles are used for diameters larger than 1.5 inches, and as these diameters are larger and heavier, are often used as single-end handles to reduce weight and ease handling during use. While always safest to replace worn gages, Trilock gages may also be reversed to extend useful life in those specific applications where the worn portion would not enter the product. Desirable for high volume inspection applications, reversible gages may be flipped end-for-end, concealing a worn end inside the handle. In this way the user enjoys double the lifetime in a single gage. For long form certification, add $15 per standard thread plug gage.
Helical coil or Screw Thread Insert Gages (STI) are used to inspect those threaded holes intended to receive a screw-thread insert. Typically used for repair of damaged threads or for a more serviceable thread, if the threaded hole gages correctly, then the threaded hole created by the installed insert will likewise be correct. Although typically X-tolerance, many sizes of W-tolerance are also available from stock for a 35% additional price.
