PRECISION THREAD CHECKER – ANSI CLASS 2A/2B TOLERANCE:Our nut and bolt thread checker complies with ANSI B1.1-2020 Class 2A/2B tolerance standards. Under ASME B18.2.2 test conditions, accuracy reaches ±0.002 inches, ensuring reliable sizing for both internal and external threads. No more mismatched hardware – just flawless accuracy. 36 SIZES – FULL SAE & METRIC COVERAGE:Identify 36 distinct sizes of bolts and nuts: 16 Metric threads from M3 x 0.5 to M14 x 2.0, and 20 Standard threads from #4-40 Coarse to 1/2-20 Fine. Each size includes both male and female threads, making this thread gauge compatible with all your standard hardware. 3 RAISED MEASURING RINGS – ENHANCED ACCURACY & STABILITY:Simply match your nuts and bolts to the corresponding slots. The 3 raised nut measuring rings are designed to optimize measurement precision – nuts sit flush and stable, eliminating the wobble common with flat boards. This thoughtful engineering ensures more accurate readings and greater stability every time you measure. Laser-etched markings stay clear, making this bolt size finder reliable for both beginners and pros alike. SOLID METAL CONSTRUCTION – NO FLEX, JUST ACCURACY.:Built with solid metal studs, not hollow ones that flex or wear out over time. This thread checker standard and metric delivers consistent, wobble-free measurements you can trust. The durable anodized finish ensures long-lasting performance in any workshop environment. CONVENIENT RULERS & EASY WALL MOUNTING:Features convenient 15CM and 6-inch rulers on the sides for quick length measurements. The pre-drilled hanging hole allows you to mount it on your workshop wall for easy access or keep it securely in your toolbox. A durable, reliable bolt measuring tool for everyday use.
