The Asimeto Plug Gauge (D/E) UNEF — Right Hand — 2B — 7/8 x 20 is a precision internal-thread gauge designed for quick, reliable verification of threaded holes. Part of the 695 Series, it serves machinists, quality inspectors, and manufacturing teams that need accurate go/no-go checks for UNC, UNF, and UNEF threads.

• Thread standards compatibility: Conforms to UNC, UNF, and UNEF internal threads, enabling versatile inspection across common Unified thread classes.
• Size and pitch: 7/8 in diameter with 20 threads per inch (7/8 x 20) for precise UNEF thread validation.
• Right-hand configuration: Right-hand orientation matches standard production threads for straightforward and consistent measurements.
• 2B tolerance class: Precision-ground to a tight 2B tolerance, delivering repeatable and trustworthy gauging results.
• Tapered design with handle: Smoothly tapered ends plus a built-in handle facilitate easy insertion into threaded holes.
• Durable construction: Robust metal body with a knurled grip and a color-coded collar for reliable handling and orientation.

This plug gauge provides fast, decisive feedback on hole threads, helping you confirm proper thread engagement and detect undersized or oversized holes early in the manufacturing or assembly process. It’s ideal for in-process checks on machines, inspection benches, and maintenance workflows where UNC, UNF, and UNEF threads are standard. The compact, durable design makes it a dependable tool in any professional shop, supporting consistent QC records and efficient setup.
