The JBO Thread Plug Gauge (GO) - Metric Fine, Right Hand, 4H, M48 x 1.5 is a go/no-go inspection tool designed to verify threaded holes meet precise metric fine standards. Ideal for quality control, machining shops, and engineers who need fast, reliable hole checks across a range of components.

Crafted from hardened steel for durability, the GO gauge offers wear resistance in demanding environments. The knurled body provides a secure grip for easy insertion, while the right-hand orientation aligns with common threading checks, helping you quickly identify properly threaded holes and maintain tolerances.

• Precise metric fine GO gauge (M48 x 1.5): Confirms hole acceptance quickly and accurately against the M48 x 1.5 standard, helping you pass or flag parts at a glance.
• Hardened steel, wear-resistant construction: Delivers long service life in busy workshops, with strong resistance to wear from repeated use and metal debris.
• Ergonomic, knurled grip with right-hand orientation: Easy to handle and align, speeds up inspections and reduces hand fatigue for consistent, efficient checks.

This GO gauge helps you speed up quality control by delivering quick, unambiguous pass/fail indications for M48 x 1.5 threaded holes. Because it uses a single, clearly defined GO condition, inspectors spend less time guessing and more time verifying, improving throughput and reducing rework. Built from hardened steel with a knurled, ergonomic profile, it stays reliable in busy workshops and supports consistent results across parts, operators, and shifts.
