Hi-Lok Protrusion Gauges
Hi-Lok Pin Protrusion Gauges are manufactured for use on all types of frangible and torque-control fasteners. These gauges
determine if the correct length pin has been installed by determining if the pin’s protrusion is between the allowable
minimum and maximum limits shown on the gauge.
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. These are complete sets that include gauges for -5 to -12 fasteners.
