What is WR?

External thread Limit gauge (LG) is used to measure former JIS metric threads and unified threads, and NO GO side ring gauges for machine work. 詳細表示

What is an Rp thread?

What is an Rp thread? It is a thread commonly called a parallel thread for JIS (ISO) pipes, and it is a parallel internal thread for pressure‑tight sealing.... 詳細表示

What is Wear Inspection Screw Ring Ga...

Wear Inspection Screw Ring Gauge is a gauge that allows you to check whether the plug gauge is worn or not. The diameter of the plug gauge decreases as it... 詳細表示

Both are GO NO side screw gauges, but there is a difference in tolerance. It is recommended to use machine work (WP / WR) at the processing site, and use in... 詳細表示

Difference Between PS and PF

Q: For PS and PF screw types, is it possible to share thread‑machining tools and gauges? A: Both are parallel pipe threads, but their tolerance settings dif... 詳細表示

W (whitworth) and U (unified) threads

W (whitworth) threads have a thread angle of 55°, and U (unified) threads have a thread angle of 60°, so it is not recommended to fit them together. 詳細表示

There are also tolerances in the angle and pitch of the gauge , and there are minute differences on the front and back. When the pitch diameter of the ext... 詳細表示

for concentricity gauge

A gauge that measures the concentricity of connected holes with different diameters is called a concentricity gauge. It is compatible with special products. 詳細表示

What gauge is used to check PS female...

Since the PS internal thread is a combination of PT external thread , a tapered plug gauge (PT) is used for pass/fail judgment. However, only if the PS inte... 詳細表示
