Testing & Measuring l Trulok Gages l Countersink Diameter Gages l Diameter XXX-X

A high precision mechanical gage for quick and accurate measurement of the major countersink diameter. The TRULOK? Mechanical Countersink Diameter Gage has proved to be the most durable and accurate countersink diameter gage for more than 60 years. Used to check countersunk diameters before the fastener is installed in the structure helping to eliminate costly reworks.

Features:
• Direct indicating scale with large-size .005 inch divisions
• Simple to use, operation involves a single push of the gage head into the countersink
• The measurement holds until the gage is reset with a short pull on the upper knob
• Maximum measuring accuracy of .002 inch. Accuracy largely unaffected by small changes of the countersink angle
• Heat-treated tool steels and micro finished parts insure accurate and trouble free operation for years to come
• A set block calibrated to NIST traceable standards is included for calibration and setting
• Each TRULOK - gage must pass a series of stringent quality tests during manufacturing
• Serial numbers are included on all gages and set blocks
• Packaged in a custom foam fitted case
