Description
Overview:
The Faithfull Screw Pitch Gauge 52, Metric, Whitworth is a compact, folding gauge for quickly and accurately identifying thread pitch on screws, bolts, studs, and tapped holes. Made from polished tool steel, it is durable and precise, with 52 individual leaves that profile common thread forms. The set covers both Metric 60-degree and Whitworth 55-degree threads, making it suitable for mixed equipment found in construction, engineering, automotive, and garden machinery. Each leaf is clearly etched with its size for fast reading. A locking device at both ends holds the selected leaf securely during measurement. The gauge measures pitches from 0.25 mm to 6.0 mm alongside the equivalent 0.01 to 0.24 inches, helping you confirm the correct tap, die, or replacement fastener before work begins.
Key Features:
- Combined 52-leaf set for Metric (60°) and Whitworth (55°) thread forms
- Pitch range 0.25 mm to 6.0 mm (0.01 to 0.24 inches) for broad coverage
- Polished tool steel construction for wear resistance and long service life
- Clear, permanent size etching on every leaf for easy identification
- Twin-end locking device holds leaves firmly while in use and during storage
- Folds into a compact pocket form to protect leaves and save space
- Suitable for checking both external and internal threads by profile matching
- Helps verify pitch before selecting taps, dies, thread repair kits, or replacement bolts
- Reliable in workshop, site, and garage environments across multiple trades
Typical Applications:
Identifying the pitch of fasteners on construction tools, garden machinery, generators, compressors, pumps, valves, and automotive parts. Useful for lathe and mill setups, fabrication, mechanical repairs, and maintenance checks. Ideal for confirming thread standards on mixed Metric/Whitworth assemblies, avoiding cross-threading, and ensuring the correct tap, die, or insert is chosen for repair or fabrication work.
