How to Use?
Product external threads should be inspected using a certified working ring gauge, and ring gauges should be inspected using a certified plug gauge.
Working ring gauges should comply with the relevant provisions of ANSI B1.1-1982 and FED-STD-H28 and H28/3. 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:
- Manufacturers should use new or minimally worn go-end ring gauges and stop-end ring gauges that are worn close to the wear limit. Inspectors and acceptors should use go-end ring gauges that are close to the wear limit and new or minimally worn stop-end ring gauges.
- Acceptance of working ring gauges should be based on the master plug gauge. A T-T or Z-T master gauge should be threaded through the working ring gauge being inspected. A T-Z or Z-Z master gauge is permitted to be threaded into both ends of the stop gauge being inspected, but the threading must not exceed one thread pitch (measured from the complete thread). Working ring gauges in use should be inspected using a T-S or Z-S master gauge. The threading into both ends of the working ring gauge being inspected must not exceed one thread pitch.
- When a dispute arises during verification, if the working ring gauge used to judge the product’s external thread as qualified meets the requirements of this regulation, the external thread of the inspected product shall be judged as qualified.
- We can provide single parameter thread ring gauges according to order requirements, with product inspection reports attached.
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.
