Wrentham Tool Group is a key supplier of recess heading tools to several major industries including but not limited to Defense, Aerospace, Automotive, Medical, and cutting edge Hi-Tech. WTG manufactures recess punches for heading everything from simple galvanized steel wood screws to complex low profile titanium Aerospace screws. WTG has expanded its product line and offerings to include the latest fastener recess innovations such as MORTORQ^®, MORTORQ^® Super, HEXSTIX^®, and TTAP^® to assist our customers with troubleshooting the most difficult applications. WTG has most recently developed a new line of BLACK DIAMOND^TM  Gages which are not only tough enough to stａnd up to the most punishing manufacturing conditions but are also elegant enough to be cased as the highest quality precision instruments of their type available to the market.

These gages are used to determine if recesses in the heads of screws are within the allowable tolerance specified in dimensional tables. These gages are available in PHILLIPS®  POZIDRIV®  QUADREX®  and Squarerecess types. The recess sizes available are 0, 1, 2, 3 and 4.

Other types such as MORTORQ®, MORTORQ® Super, or TORQ-SET® can also be provided.

These gages are used to check the driver fit in the screw recess. These are available in PHILLIPS®, POZIDRIV®, QUADREX®, and Square Recess types. The recess sizes available are 0, 1, 2, 3 and 4.

Upon request test blocks can be made for other recesses such as  TORX®, MORTORQ®, and MORTORQ® Super.

Note: Available with either English or Metric Dial Indicators.

These gages are used to check driver fit on a "GO-NO GO"basis. These gages are available in PHILLIPS®,  POZIDRIV®, QUADREX®, and Square recess types. The recess sizes available are 0, 1, 2, 3 and 4.
