Description
Overview:
The Sealey Screw Pitch Gauge Set, part number AK72SPG, is a 30-piece folding tool for identifying and measuring American National thread pitches on fasteners and components. It uses precisely profiled steel blades, each stamped with its pitch, to match the thread form accurately. Covering both UNC (coarse) and UNF (fine) threads from 4 to 62 threads per inch (tpi), it spans approximate metric pitches from 6.35 mm (4 tpi) down to 0.41 mm (62 tpi). The compact, pocket-friendly holder keeps the leaves protected and ready for quick use. Ideal for workshop, site, and garage work, it helps you confirm the correct pitch before selecting taps, dies, or replacement bolts on machinery, plant, vehicles, and general assemblies. Model: Sealey AK72SPG.
