Heavy Hex Size Reference card

Heavy Hex Instructions for use

A plastic Heavy Hex Gauge to identify the measurement of nut and stud sizes. On the back is a Metric scale to identify standard Heavy Hex Nuts and studs. A note from experience, plastic is ok if you are working Turnarounds as the eqyipment is at ambient temperature. Don't buy this if you work on steam lines or equipment over 410°f or 210°c.

Inch and Metric Clear Card Thread Checkers. These are used as a thread checker to identify the standard thread pitches used with Heavy Hex sizes.

Just an FYI for the differences between "GOOD", "BETTER", & "BEST":
"GOOD" the hex gauge is made of plastic.
"BETTER" The hex gauge is made of anodized aluminum. Inch on front and metric on back.
"BEST" has two hex gauges where Inch is stainless steel with Inch on front and thread profiles on the back. The other hex gauge is made of anodized aluminum with Metric on front and thread pitches on the back side.
