Description
The JBO Plug Gauge - UNC (STI) Right-Hand is a precision measuring tool designed to verify Unified National Coarse (UNC) screw thread inserts (STIs). Engineered for reliability in manufacturing, automotive, and aerospace environments, it helps inspectors confirm the pitch diameter and proper engagement of UNC STI inserts with consistent, repeatable results. The gauge features an ergonomic knurled body with a contrasting center stripe and color-coded end collars for easy orientation during checks.
This specific gauge is sized No. 10 x 24, 2B tolerance, and includes DAkkS-calibrated traceability to ensure measurements meet international standards. The right-hand configuration supports standard handling in STI insert work, while the robust construction and precisely machined ends are built for repeated use in busy workshop environments.
