Straight Pipe Threads


R series thread plug gages, both Rc (BSPT) and Rp (BSPP), G-GR-LD are designed to inspect the pitch diameter and functional thread for internal-thread components. All plug gages are available with Certificate of Accuracy documentation. Both tapered and staight R series threads use the same gages to inspect per DIN EN 10226-3, ISO 7-2. This new worldwide standard replaces previous standards such as DIN 2999-2 to -6, BS 21, NF-E 03-165, and UNI ISO 7-2:1984.
