Schrew pitch gauge 52 blades

Diesellan 52-blade thread pitch gauge is designed as a professional tool when fast, accurate, and reliable identification of thread type and thread pitch is essential. This tool combines both metric (60°) and Whitworth standard (55°) thread profiles in one compact body. A wide range of gauges makes the gauge exceptionally versatile – covering the most common European, British, and Imperial threads. The tool features 52 precision-ground steel blades (Metric (MM 60°): 0.25–6.00 mm and Whitworth (WW 55°): 4–62 TPI), making it ideal for both European and American machinery, equipment, and spare parts. Ideal for industrial maintenance departments, repair shops, and machine shops. Many maintenance tasks begin with an unknown thread type. In this case, the thread pitch gauge is an indispensable tool, as selecting the wrong thread type can lead to breakages, jams, or safety hazards.

WW 55° 4–62 / MM 60° 0.25–6.0 (DIN 13/14)

Key features:

- WW 55° = Whitworth threads with 55° angle
- 4–62 TPI = Whitworth/imperial threads per inch (TPI) range
- MM 60° = metric thread profile at 60° angle
- 0.25–6.0 mm = metric thread pitch
- DIN 13/14 = German standards defining metric and Whitworth threads and their profiles.
