Omega Technologies OM2-1522HST Standard Hi-Lite Protrusion Gauges, 5PC Set. Omega Technologies 5PC Set of Protrusion Gauges for nominal diameter Hi-Lok® and Hi-Tigue® Fasteners in sizes 5/32”, 3/16”, 1/4” 5/16”, and 3/8”. This Omega Technologies Protrusion Gauge Set replaces Hi-Shear® 2-1522HST Gauge Set.

Omega Technologies Pin Protrusion Gauges are designed for use on all types of frangible and torque-control fasteners. Omega Technologies Protrusion Gauges determine if the correct length pin has been installed by determining if the pins projection is between allowable minimum and maximum ranges shown on the gauge.

Omega Technologies Protrusion Gauges are available for Hi-Lok®, Hi-Lite®, and Hi-Tigue® Systems. To select the correct gauge for the fastener, select the one that corresponds to the appropriate pin diameter. If the pin falls short of the limit or exceeds the maximum, then it must be removed and a more appropriate size needs to be selected.

If you exceed the maximum limit then a shorter pin is required, and if you fall short of the minimum limit then a longer pin is required. The correct pin will lie between the maximum and minimum limitations that gives a proper ratio of grip to protrusion. These complete sets include gauges for -5 to -12 fasteners and the related part number is 2-1522-B.

Omega Technologies Protrusion Gauges are constructed of full-hard, electro-chem etched, durable 301 stainless steel, these gauges are assembled on a chain for easy selection and use. A large hole facilitates manipulation of the leaves, and extra large RED markings facilitate correct gauge selection. Rounded corners reduce risk of scratching surrounding surfaces. Omega Technologies Gauges are .88″ high and .88” wide.
