Introducing the Truthread Plug Gauge (UN, Right Hand, 2B, 1.3/8x8). This precision tool checks the internal threads of threaded holes against UNC, UNF, and UNEF standards, helping engineers, machinists, inspectors, buyers, tradespeople, and hobbyists verify thread fit quickly and reliably. Its tapered plug design and easy-to-grip handle ensure smooth insertion and consistent results for everyday QC, assembly checks, and maintenance tasks.
- UN thread standards compatibility: Verifies internal threads for UNC, UNF, and UNEF, so you can confirm correct thread engagement in one quick check.
- Tapered plug design with ergonomic handle: The tapered tip slides into threaded holes easily while the handle provides precise control, reducing insertion effort and protecting threads during inspection.
- Precise size and tolerance for 1.3/8x8 right-hand threads: With 2B tolerance, this gauge delivers repeatable, reliable measurements across parts and holes in standard UNC/UNF/UNEF applications.
Use the Truthread Plug Gauge to streamline quality checks, calibration workflows, and routine maintenance. Its robust construction and tight tolerances contribute to long tool life and dependable performance, helping you make confident decisions about threaded assemblies and ensure consistent results on the shop floor.
