Metric and Imperial Thread Pitch Gauge, 52 Blades

Compare a thread profile with a 52-blade gauge for metric 60° and imperial 55° threads.

Compare metric and imperial thread pitch

• ✅ Identify a matching pitch – Different blade profiles let you compare the spacing against the thread.
• ✅ Check two thread systems – Metric and imperial blades cover the listed 60° and 55° profiles.
• ✅ Fold blades into one tool – The pivoting arrangement keeps the profiles together for storage.

Use the marked blades for comparison; a pitch match does not by itself establish thread diameter or a complete fastener specification.

• Specifications: stainless steel; 52 blades; metric 0.25–6.0 mm; imperial 4–62 TPI; approximately 6.5 × 1.8 cm.
