  • High Temperature Durability: Constructed from laser-engraved anodized 6061 aluminum, the HexSizer withstands extreme temperatures up to 1000°F (538°C), making it perfect for hot units, live steam lines, and other high-heat environments.
  • Versatile Inch & Metric Compatibility: Covers both Inch (1-1/16" to 6-1/8") and Metric (32mm to 165mm) sizes, serving as a comprehensive bolt and nut size identifier for any job.
  • Portable and Ready for Use: Comes with a detachable tether and vinyl sheath for easy carrying and accessibility, fitting perfectly in a pocket or on a keychain.
  • Essential for industrial pros: A must-have for Millwrights, Pipefitters, and Techs using hydraulic, pneumatic, or electric torque wrenches in high-temp environments. A bolt and nut sizer also makes a great gift for them.

The gauge only measures Inches. There is no Metric! One side has Inch gauge and the other side is blank. Might be a manufacturing defect.Otherwise it is a great little tool for quick measuring.

This product is really a game changer. Takes all the guess work out. Also Wes the owner of this company goes above and beyond to make sure his customers are taken care of. Hard to find that these days.
