Klein Tools 630-5MM 5mm Hollow Shaft Electronic Nut Driver

Product Description

The KLEIN TOOLS 630-5MM is a 5 mm electronic nut driver built for precision fastening work on electronic assemblies, control panels, and low-voltage equipment. The hollow shaft design allows the driver to seat fully over long or protruding threaded studs without bottoming out, which is essential in tight panel enclosures. The chrome-plated shaft resists corrosion and wear during repetitive use. At 6.75 inches overall length with a 3-inch shaft, the tool balances reach and control. The cushion grip handle reduces hand fatigue during extended service calls. This driver meets ANSI and ASME standards and carries a lifetime warranty from Klein Tools.

The 630-5MM is suited for electricians, HVAC technicians, and electronics service professionals working on terminal blocks, relay sockets, control boards, and similar equipment where a 5 mm hex fastener is common. The hollow shaft is especially useful when driving nuts onto long screw terminals found in breaker panels, variable frequency drives, and low-voltage control enclosures. It is a single-piece hand driver intended for bench work and field service alike.

Installation Notes

This tool is used by electricians and electronics technicians for hand-tightening metric hex nuts on terminal hardware. De-energize and lock out all equipment before servicing any panel or control enclosure. Use appropriate torque judgment for the fastener material and application — electronic hardware is typically low-torque. Do not use this driver as a pry tool or apply lateral force to the shaft.
