Gages Features:
1) Metric thread working plug gauge inspection environment: standard temperature 20°C ± 1°C, standard condition measurement force is zero.
2). Metric thread working plug gauge inspection method: Use the “three-needle method” with a Length measuring instrument to measure a single pitch diameter. Use a tool microscope to measure thread pitch, half angle, minor diameter, and clearance groove.
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?
Metric Thread Working Gauge Use: Product internal thread inspection should use a certified working gauge that complies with the relevant provisions of ISO1502 and ASME B1.16M . To reduce disputes during inspection and acceptance, it is recommended that the manufacturer, inspector, and acceptor use the same certified gauge. If using the same certified gauge is difficult:
1) Manufacturers should use new or minimally worn GO-end plug gauges and NO GO-end plug gauges with wear close to the wear limit; inspectors and acceptors should use GO-end plug gauges close to the wear limit and new or minimally worn NO GO-end plug gauges.
2) GO-end (T) thread plug gauges have a full profile, and should be screwed through when used to inspect the effective pitch and major diameters of a product’s internal threads.
3) NO GO-end (Z) thread plug gauges have a truncated profile and should be screwed in when used to inspect a single pitch diameter of a product’s internal threads. The screwing should not exceed two thread pitches.
4) A working plug gauge used to determine the acceptance of a product’s internal threads is considered acceptable if it meets the applicable standard.
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 plug gauge with gage inspection report according to order requirements. But the prices will be requested.
