Sealey AK73SPG 52 Piece Screw Pitch Gauge Tool

The Sealey AK73SPG is a comprehensive 52-blade screw pitch gauge designed for accurate thread identification across BSW and metric standards. This folding gauge set features individually stamped blades with precise thread profiles, making it an essential measuring tool for engineers, mechanics and maintenance professionals who need to quickly identify thread pitches on bolts, screws and threaded components.

The tool covers an extensive range of thread measurements, including BSW threads from 4 to 62 TPI and metric threads from 0.25mm to 6mm pitch. Each blade in the folding design is clearly marked for easy reference, allowing tradespeople to match threads efficiently when sourcing replacement fasteners or identifying unmarked components. The compact folding configuration keeps all 52 blades organised in a single portable unit, ideal for workshop benches or field service applications.

At just 0.07kg, this screw pitch gauge is lightweight enough for technicians to carry in toolboxes without adding significant weight. The gauge proves particularly valuable when working with older machinery where thread standards may be unclear, or when dealing with mixed metric and imperial fixings commonly found in UK industrial and automotive environments.

• Folding 52-blade design keeps all thread sizes organised in one compact tool
• Individually stamped blades provide accurate thread profile matching
• Dual thread coverage for both BSW and metric standards
• Lightweight construction at just 0.07kg for easy portability
