The HexSizer® Heavy Hex Gauge™: The Fastest Way to Size Industrial Nuts and Bolts
In heavy industry, time is money—and sometimes, it’s a lot of money. A wrong-size socket can stop a maintenance job at a refinery, delay an entire crew, and cost tens of thousands of dollars before the right tool even arrives. That’s why the HexSizer® Heavy Hex Gauge™ is becoming a must-have for bolting professionals in power generation, oil & gas, chemical plants, and beyond.
The Problem:
Traditional measurement methods tell you to measure “across the flats” (A/F) of a nut. But when the nut is installed on a stud, that stud blocks your ruler or calipers from measuring across the flats. Even if you could measure it, ASME standards allow nuts to be slightly smaller than their nominal size—leading to confusion over whether you’re looking at an imperial or metric fastener.
The Solution:
The HexSizer® Heavy Hex Gauge™ measures from one flat—avoiding stud interference—and shows only standard heavy hex sizes, both inch and metric. No extra lines. No fractional guesswork. No wondering if you need a 2” or a 2-3/16” socket or wrench.
Why It Matters:
When you’re on the job, confidence in your measurement means confidence in your work. You can walk a site, size every nut and bolt in minutes, and know exactly what tools to bring—preventing costly downtime and avoiding dangerous improvisations like torch-cutting bolts.
Key Benefits:
- Works on installed nuts where other tools fail
- Measures both nut size and matching stud size
- Compact enough for wallet or lanyard
- Anodized aluminum construction resists heat up to 1000°F
- Covers ASME 18.2.2 inch and metric standards
Who It’s For:
Millwrights, pipefitters, steamfitters, field maintenance techs, inspectors, and planners in industries like power generation, oil & gas, chemical processing, mining, and structural steel.
The Bottom Line:
The HexSizer® Heavy Hex Gauge™ doesn’t just save time—it saves money, contracts, and in some cases, safety hazards. In a high-pressure industrial environment, having the right size is more than convenience—it’s mission critical.
