This both a stud, bolt and nut sizer. Rather than measure across the flats, the Heavy Hex Gauge nut measuring tool measures as a nut checker from one flat or one side of the hex nut, bolt head or stud.

It is both a bolt sizer and a nut sizer made for jumbo nuts and bolts and large head bolts as a sizing gauge that identifies only standard sizes. The bolt checker bolt sizing gauge or bolt size tool measures the outermost part of the thread so it's easy to identify a standard bolt size. This also has a metric bolt sizer and metric nut sizer Make fast work at sorting your bolt bin. Most technicians will wear this sizer on their lanyard with their badges.
