Schrew pitch gauge 58 blades

New generation of thread gauge for multi-standards!

Diesella's new 58-blade thread gauge is designed for situations where multiple thread standards—metric, Whitworth, and RG pipe threads—are encountered at the same workstation. This model provides broader coverage and is designed to withstand daily professional use in industries such as manufacturing, machine shops, maintenance teams, and installation work. The completely redesigned blade set covers both the WW 55° (4–62 TPI) and MM 60° (0.25–6.0 mm) ranges, and the gauge also includes RG 8–28 pipe thread inspection blades—a combination that is uncommon in similar gauges. The 58-blade model is designed for situations where the worker cannot know in advance what thread standard will be encountered.

Three different standards in one frame:
- WW 55° 4–62 TPI – British and Imperial threads
- MM 60° 0.25–6.0 mm – metric thread profiles
- RG 8–28 – pipe threads (R, G, BSP types on request)
