Set of 5 precision protrusion gauges for nominal diameter Hi-Lite fasteners, Sizes: 5/32″, 3/16″, 1/4″, 5/16″ & 3/8″ larger than 2-1522HST gauges. These gauges feature the same “min” and “max” protrusion limits as 2-1522HST but with much tighter tolerances. These gauges may be used in place of 2-1522HST or 2-1522HST gauges. The larger gauges measure 1.05″ square and permit greater “reach” to check pins even in the collars have particularly wide bases or washers. Each set is serialized for calibration and control purposes. All 6 pieces of each bear the same serial number.
