The Drilling Tool Thread Gauge UN BSW NPT NPTF is a precision instrument used to verify API internal and external threads. It conforms to API specification 5B and API specification 7, covering a broad selection of thread profiles. The gauge set includes CSG, LCSG and LP sizes from 4‑1/2" to 20" for CSG and LCSG, and 1/8" to 12" for LP. Additional gauges cover BCSG (4‑1/2" to 6"), TBG and UPTBG (1.050" to 4‑1/2").
These gauges are normally machined from hardened tool steel and heat‑treated to achieve a hardness of around 60 HRC, providing long‑term dimensional stability. The typical tolerance for thread measurement is ±0.001 inch, matching industry expectations for oilfield equipment. Surface finish is usually a black oxide coating to resist corrosion in harsh environments. The design follows the standard API geometry for each thread class.
Oilfield service firms, drilling contractors and maintenance teams use the gauges to ensure proper thread engagement before assembly. The supplier offers bulk packaging suitable for shipment in protective cases, with FOB terms commonly applied, though exact incoterms and MOQ should be confirmed directly. Payment can be arranged via L/C or T/T upon agreement. Buyers are advised to request the latest calibration certificate and any applicable quality documentation before finalising the order.

Before placing an order, verify that the gauge dimensions match the API 5B and API 7 ranges required for your application. Request a recent calibration certificate and ask the supplier to confirm the material grade and coating condition of the gauges. Because the supplier’s response record is empty, a preliminary phone or video call can help establish reliable communication channels.
Logistics for this product are usually handled on an FOB basis, but buyers should confirm the preferred incoterm, expected lead time and any freight forwarder requirements with the supplier. Payment terms are typically L/C or T/T; ensure that the payment schedule aligns with your company’s risk management policy. Clarify any minimum order quantity or packaging preferences early to avoid later adjustments.
When receiving the shipment, inspect the protective cases for any damage and verify that the gauges are free from wear or corrosion. Conduct a functional check against a known master thread to confirm accuracy within the ±0.001 inch tolerance. Retain the calibration certificate and any material test reports as part of your quality documentation for future reference.
