What is the size 10 mean on the nut sizer part? I need to find a tap for a size 10 hole. Thanks** A: Howdy Michael. The 10 corresponds to a number 10 machine screw. According to the Standard US Machine Screw Sizes, a number 10 comes in two thread sizes: a 10-32 and a 10-24. The 32 and 24 refer to the number of threads per inch. So, if you've used the gauge and determined you have a #10 screw, you'll then need to decide if you need the "fine" thread, 32 or the "coarse" thread, 24. Your local hardware store could help you determine which you need and what tap size you'll need. **Q: Is it both SAE and Metric?** A: Yes it is both metric and SAE. On the backside it also has United States Thread Pitch and Metric Thread Pitch. Both Inch and mm bolt length are on longer sides. Bolt dia. goes from 3 to 22 metric and 1" to 1/4" SAE. The shoulder posts for nuts is more limited but has both metric and SAE. **Q: what is the smallest and largest sizes?** A: SAE screw = 1 inch to #4 Metric screw = 22mm to 3mm SAE nut = 5/8 inch (no gauge for metric nuts) Screw metric pitch from 0.70mm to 2.00mm Screw SAE pitch from 10TPI to 24TPI **Q: Are you able to use this as a drill gauge, or would I need a separate gauge for that?** A: No, you need a separate gauge for that. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***U on February 18, 2024* ### ⭐⭐⭐⭐⭐ Review *by D***L on March 30, 2011* ### ⭐⭐⭐⭐⭐ Review *by R***F on September 20, 2025* ## Frequently Bought Together - Boltsize-It Gauge, Blue - IRWIN Drill Bit Gauge, 1/16-to-1/2-Inch, 29-Hole (12092) - Milescraft 4009 Fence Clamps - 2 pack Universal Clamps with 3/8" Rod for Table Saws, Mitre Saws, Router Tables and Clamping Squares --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co/products/3654828-gauge-blue](https://www.desertcart.co/products/3654828-gauge-blue) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-05-03*
