Description
Thread Pitch Gauge for Metric and Inch Threads
This steel thread pitch gauge is designed to measure screw thread pitch on both internal and external threads. It supports two thread angle standards — 55 degrees (Whitworth/BSP style) and 60 degrees (metric/unified style) — making it a versatile tool for identifying a wide range of fastener types.
Key Features
- Dual angle coverage: Measures 55° and 60° thread profiles in a single tool
- Wide pitch range: 55° blades cover common imperial pitches (TPI); 60° blades cover metric pitches from 0.5 mm to 7.0 mm
- Steel construction: Quench-hardened for durability and long-term accuracy
- Rotary switch adjustment: Flip individual blades out freely for quick comparison
- Compact size: Approximately 6.7 × 1.7 × 1.3 cm — fits in a tool bag or pocket
How to Use
Select a blade and hold it against the thread profile of the fastener or workpiece. If the blade teeth seat flush without gaps, the pitch matches. Work through the available blades until you find the correct fit. This method works on bolts, nuts, pipe fittings, and machined parts.
What to Check Before Buying
Confirm which thread standard your application requires — metric or imperial — and verify the specific pitch values in the listing variant. Check that the blade range listed covers the pitches you need most often. Package includes one thread pitch gauge tool.
