Thread Checker Gauge for Nut and Bolt, SUS304 Stainless Steel, 15 Standard & 12 Metric Sizes

Product Description ANSI Standard Precision Check Class 2B Go & No Go

The threaded hole's specified tolerance can be determined with the Thread Plug Gauge, as the smooth insertion of the Go end indicates compliance while the No Go end does not fit at all.

Similarly, the Thread Ring Gauge can verify the specified tolerance of the bolt's thread, with the smooth fit of the Go end indicating compliance and the No Go end failing to fit at all.

Crafted with CNC-machined anodized aluminum alloy and hardness SUS304 stainless steel thread, the bolt and nut Identifier gauge ensures maximum thread strength and ultimate precision. Its protective anodized finish and laser etched markings ensure durability.

This gauge can quickly identify 27 different sizes, covering the most common thread sizes. With a nut and bolt checker for each size, it includes metric thread sizes from M4 x 0.7 to M12 x 1.75, and imperial threads from #6-32 Fine to 1/2-20 Fine.

Featuring 8 different size Drill Gauges with measurements of 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 1/4inch, and 1/2inch, this nut and bolt thread checker allows for quick and easy gauge of drill bits, especially older or unmarked ones.

The multifunctional design includes a built-in ruler on both sides, offering measurements of 4-1/4 inches and 11 centimeters. Four rubber foot cups and two pre-drilled holes on the top allow for easy placement on a work bench or installation on the wall.

The bolt identifier board is an accurate and easy-to-use thread verifier for both nuts and bolts. It assists in quickly identifying or organizing a collection of screws and nuts, making it a helpful tool for plumbers, handymen, repairsmen, auto mechanics, and machinists.
