All these ISO metric thread gauges are made according to standard ISO1502 and ASME B1.16M .
Meantime, we also can provide custom production service for special metric thread gages, for example, Special diameter, special pitch, pre-plated and left hand etc. Usually we need two weeks to finish special ring gauges, and ten days to finish special plug gages. Only one pc is acceptable.
- Material：Oil hardened tool steel-Gcr15, high wear resistance.
- Hardness: 58-62 HRC
- Ring gages are solid; Plug gauges are Taperlock- double ends with one handle. our solid ring gages can be used directly, no need setting plug gages to test them in advance. The advantage of Taper-lock style is when one end worn out, one new end can be replaced quickly and easily.The handle and end in good condition can be used again.
- All gages are brand new
- Gage manufacturer ISO9001 certified
- gaugestools know the importance of controlling temperature and humidity when testing gages, the temperature will be 20 degree +- 0.5 degree, the humidity will be 45%-65%
- Long form calibration certificate from ISO17025 accredited lab can be provided, but it need to be told in advance, and need extra costs.
- We can provide laser marking service on the gauges. For example, clents’ Logo.

ISO Metric thread with 60 degree thread angle.
The Go end of thread plug gage checks the smallest size of pitch diameter D2,the smallest size of major diameter.It also check some thread deviation, for example, pitch, thread profile angle deviation. The go end should go through the whole thread without using force. the Nogo end of plug gage checks the largest size of pitch diameter. The NOGO end should be stopped during the first 1-2 turns.
ISO metric thread is the most commonly used general-purpose mechanical fastening thread,which have great influence in mechanical production field. ISO metric thread’s standard is one of the most important mechanical Base standards.
