Gages Features:
1) Metric thread working ring gauge inspection environment: standard temperature 20°C ± 1°C, standard condition measurement force is zero.
2). Metric thread ring gauge inspection: GO-end (T) thread ring gauges are inspected with MASTER plug gauges TT and TZ; NO GO-end (Z) thread ring gauges are inspected with MASTER plug gauges ZT and ZZ.
3）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.
4）The standard recommends common fits 6H/6h and 6H/6g; the G tolerance zone can be used for threads before plating. if no special note, ring gage 6g, plug gage 6H will be choosed。
5) Tolerance Available : Plug gauge thread class: 4H,5G,5H,6G,6H,7G,7H,8G,8H; Ring gauge thread class: 4h,5g,5h,6g,6h,6e, 7h,8g,8h.
How to Use?
Instructions for Using Metric Thread Ring Gauges:
Product external threads should be inspected using a qualified working ring gauge, and working ring gauges should be inspected using a qualified plug gauge.
Working ring gauges should comply with the relevant provisions of ISO 1502. To reduce disputes during inspection and acceptance, it is recommended that manufacturers, inspectors, and acceptors use the same qualified gauge. If using the same qualified gauge is difficult:
1)Manufacturers should use a new or minimally worn go-end ring gauge and a stop-end ring gauge worn close to the wear limit; inspectors and acceptors should use a go-end ring gauge close to the wear limit and a new or minimally worn stop-end ring gauge.
2)Acceptance of working ring gauges should be based on the plug gauge. The go-end or stop-end gauge should be threaded through the working ring gauge being inspected. The go-end or stop-end gauge should not be screwed into the working ring gauge being inspected by more than one thread pitch (measured from the full thread). Working ring gauges in use should be calibrated using either a through-loss or stop-loss calibration. The amount of engagement between the two ends of the working ring gauge being tested must not exceed one thread pitch.
3)In the event of a dispute during calibration, the working ring gauge that determines the external threads of the product being tested are qualified if it meets the requirements of this procedure. The product’s external threads are considered qualified.
Gages Certification:
Long form calibration certificate from ISO17025 accredited lab can be provided, but it need to be told in advance, and need extra costs.
Special Order:
1) 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 3~4 weeks to finish special ring gauges, and ten days to finish special plug gages. Only one pc is acceptable.
2) Super Size thread Gages is available, till to Max Size: 1000 mm ,come with long form calibration certificate.
3) We can provide laser marking service on the gauges. For example, clents’ Logo.
4）We can provide full parameter working ring gauge with gage inspection report according to order requirements. But the prices will be requested.
