SAE Nut and Bolt Gauge

thingiverse

This SAE nut and bolt gauge is designed to complement its metric counterpart, which was shared previously. The upgraded version boasts significant improvements over its predecessor. Every bolt size, with the notable exceptions of 6, 8, 10, and 12, is now securely fastened using a press fit instead of traditional threading. This ingenious design enhancement ensures the bolts remain firmly in place, providing enhanced precision and accuracy. I acquired all necessary hardware for approximately $7.00. In contrast, high-quality gauges can retail for as much as $75.
