The Xcelite XPND600 6-Piece ESD Safe Precision Nut Driver Set includes six nut drivers (sizes 7/64", 1/8", 9/64", 5/32", 3/16", 7/32"). The nut drivers are ESD safe to provide protection to sensitive items. The chrome-molybdenum vanadium steel blades provide superior strength, while the fast-turning swivel caps ensure optimum control and precise centering. The black oxide tips provide longer wear life, and the no-roll handle design keeps drivers from rolling off uneven surfaces. The set is supplied with a case to keep drivers safe and securely stored.
