The Asimeto Plug Thread Gauge (D/E) is a precision internal-thread gauge designed to quickly verify threaded holes. Built for machinists, inspectors, and maintenance professionals who work with UNC, UNF, and UNEF threads, this right-hand gauge delivers fast, reliable go/no-go readings in a compact, hand-friendly form.

• Thread Standards: Conforms to Unified National Coarse (UNC), Unified National Fine (UNF), and Unified National Extra Fine (UNEF) thread standards for versatile hole inspection.
• Size and Fit: Compact D/E size with a 7/8 in major diameter and 9 TPI (threads per inch) to match common through-holes and tapped holes.
• 2B Tolerance: Tight 2B tolerance ensures consistent measurements across tools and parts, reducing guesswork during assembly checks.
• Right-Hand Configuration: Specifically designed for right-hand threads, providing accurate orientation and straightforward readings.
• Tapered Design with Knurled Handle: Precisely tapered plug paired with a textured handle for smooth insertion into threaded holes and easy removal.
• Durable Construction: Sturdy metal body with a knurled surface and protective features designed to withstand routine workshop use.

Using this gauge, technicians can quickly determine if a hole’s internal threads will properly accept a fastener, avoiding mismatches, rework, and downtime. The tapered tip guides the plug into the thread without cross-threading, while the 2B tolerance yields dependable go/no-go results across batches and returns consistent measurements for quality records. The rugged construction supports daily use in machine shops, maintenance bays, and assembly lines, and the red indexing band helps orient the gauge quickly in busy workspaces.
