The Heavy Hex Gauge is a simple ruler that, from one flat, measures and identifies the ASME Heavy Hex nut sizes and corresponding ASME stud sizes that are commonly found in Power Generation, Chemical Plants, and in the Oil & Gas industries. This Heavy Hex Gauge is made for high heat. It is sharply Laser engraved anodized aluminum so it can be used at temperatures a little over 1000°f / 538°c without losing integrity. Included is a detachable tether and vinyl sheath to protect it. It shows only the standard sizes so there are no other measurements to confuse you. It's the fastest way to confirm a nut size on industrial job sites.
