Little things not only mean a lot, they can also explain a lot. Consider a spent blind-rivet mandrel, which is only 1 to 2 inches in length, but has tiny markings that provide a wealth of information to veteran rivet-tool-supplier salespeople like Michelle Donath at Yamazen Inc.

The ASSEMBLY Show hosts some 38 suppliers of screwdrivers, nutrunners, screw feeders, torque-reaction arms, rivet guns and other fastening products.
