Truthread Plug Thread Gauge (D/E) - UN - Right Hand - 2B - 1.1/4x8

The Truthread UN Plug Gauge is a precision measuring tool crafted to verify the internal threads of holes. Designed to cover UNC, UNF, and UNEF standards, this Right Hand plug gauge is sized for 1-1/4 x 8 and built to 2B tolerances, delivering reliable, repeatable results for a wide range of applications. It’s an essential test aid for machinists, quality inspectors, and assembly teams who need quick, accurate thread verification.

Its tapered nose and built‑in handle make insertion and withdrawal easy, even in deeper or harder‑to‑reach holes, helping you assess fit and thread quality without risking damage to the threads. The rugged construction and precision engineering ensure consistent measurements across multiple checks and operators.

• UN thread compatibility: Conforms to UNC, UNF, and UNEF standards, enabling quick verification of multiple thread types with a single gauge and reducing tool clutter.
• Tapered design with a handle for easy use: Facilitates smooth insertion and removal, minimizes thread damage, and speeds accurate inspections in various hole depths.
• 2B tolerance for reliable results: Tight tolerances paired with 2B class guidance ensure repeatable measurements and dependable quality checks.

Used in quality control, maintenance, and production settings, this plug gauge helps you confirm thread integrity early, reducing downstream assembly issues, minimizing rework, and keeping your workflow moving smoothly. It provides confident, fast assessments that support better part fit, reduced downtime, and consistent results across tools and teams.
