Klein Tools 630-3/16 Nut Driver 3/16 Inch Hex Hollow Shank

Product Description

The KLEIN TOOLS 630-3/16 is a 3/16-inch hex nut driver built for trade professionals who need reliable fastener control in tight or extended-bolt applications. The hollow shank design allows the driver to slide over long bolts and threaded studs, eliminating the clearance problems that stop solid-shank drivers cold. The cushion grip handle provides a comfortable, slip-resistant hold during extended use. At 0.2 pounds, it is light enough for all-day carry on a tool belt. Electricians, HVAC technicians, and plumbers reach for this driver when working panel knockouts, equipment covers, and terminal blocks that call for 3/16-inch hex fasteners.

This nut driver is suited for residential and light commercial service work where 3/16-inch hex fasteners appear on electrical panels, HVAC equipment cabinets, conduit fittings, and similar assemblies. The hollow shank is particularly useful on installations where fastener threads extend well beyond the nut face, a common situation on equipment mounting studs and buss bar hardware. It is sold individually by the unit.

Installation Notes

This tool is installed by hand with no power required. Always de-energize electrical equipment before accessing panels or terminal areas where this driver will be used, in accordance with NFPA 70E safe work practices. Ensure the hex drive is fully seated on the nut before applying torque to avoid fastener rounding. Inspect the cushion grip and shank for damage before each use.
