Hi-Lok Go-No-Go Pin Protrusion Gauge 2-1522HST

PIN PROTRUSION GAUGES (FOR HI-LITE®) – MODEL 2-1522HST

Also known as Go-No-Go Gauges. Use these gauges for inspection of pins for correct grip length after installation. Includes gauges for 5/32″, 3/16″, 1/4″, 5/16″ and 3/8″.

To determine if the correct length pin has been installed, the tip of the pin protruding from the structure must fall between the recommended allowable maximum and minimum limits. Checking pin protrusion is easily accomplished with the proper Pin Protrusion Gauge. Distinct Gauge Sets are available for the Hi-Lite® system. Using the set for the fastening system, select the gauge for the pin diameter in question. If contact is made at the maximum limit, the pin should be removed and replaced with a shorter pin. If contact is not made at the minimum limit, the pin should be removed and replaced with a longer pin. Any protrusion between the upper and lower limit is satisfactory.
