Nut and Bolt Thread Checker Board with 30 SAE and Metric Sizes, 19 Drill Bit Gauges and Laser-Etched Scales – Manalete

A nut and bolt thread checker identifies common SAE and metric fasteners at a glance, reducing trial and error during repair or assembly. Manalete mounts precision steel bolts in a red CNC-machined anodized aluminum board with high-contrast labels.

The board checks 30 thread sizes from M2 x 0.4 to M14 x 2.0 and #2-56 to 5/8-18. Nineteen drill-bit gauge holes cover six metric and thirteen imperial sizes, while etched edge rulers and mounting holes support bench or wall use.
