Our measuring tools mainly include Thread Plug Gauge, Thread Ring Gauge and Rebar Coupler Taps.

The Thread Plug Gauge is used to check an internally threaded part. In general, the thread plug gauge will be double ended, with one end carrying the GO gauge and the other end the NO-GO gauge. Its raw material is: Bearing Steel Gcr15. Its hardness can reach HRC58~62.

The Thread Ring Gauge is a cylindrical ring of a thermally stable material, steel, and is used for checking the outside diameter and pitch diameter limits on threaded parts. The GO and NO-GO rings are normally seperate pieces. Its raw material is: Bearing Steel Gcr15. Its hardness can reach HRC58~62.

Rebar Coupler Tap is used for machining internal threads in holes, and its characteristics include: high precision thread processing; easily handling; processing mechanically or manually; making threads for complex shapes and large workpieces.

Main classifications for specification：

1. Metric size;
2. B.S.W;
3. U.N;
4. Accept all Customized specification.

Due to each specification of measuring tools can be made or customized, the plug gauge, ring gauge and rebar coupler taps have help us to win a lot of customers from many countries, including France, Malaysia, Korea, Singapore, Indonesia, India, Egypt, Russia, Pakistan, Denmark and Thailand etc.
