The Sealey AK73SPG is a 52-blade screw pitch gauge for identifying thread pitches on bolts, screws and threaded components. Its folding design keeps the blades together in one compact unit.
The gauge covers BSW and metric thread types. BSW measurements range from 4 to 62 TPI, while metric pitches range from 0.25 mm to 6 mm. The blades have individually stamped thread profiles and clear markings for reference when matching a thread.
It can be used to identify thread pitches when checking fasteners or unmarked components, including where thread standards are unclear or metric and imperial fixings are mixed.
