Klein Tools 630-9/16 Cushion-grip Nut Driver 9/16 Inch

Product Description

The KLEIN TOOLS 630-9/16 is a cushion-grip, hollow-shaft nut driver designed for fastening and loosening hex nuts and bolts in tight, professional-grade work environments. The 9/16 inch hex opening and 4 inch hollow shaft allow the driver to seat fully over threaded rod or long bolts without bottoming out, which is a critical advantage in electrical panel, conduit, and equipment enclosure work. The cushion-grip handle provides a firm, comfortable grip during extended use. This tool is intended for licensed electricians, HVAC technicians, plumbers, and other trade professionals who work with hex fasteners regularly.

The 630-9/16 is suited for residential and light commercial applications where 9/16 inch hex fasteners are common. Typical use cases include securing electrical enclosures, panel knockouts, conduit fittings, and mechanical equipment fasteners. The hollow shaft design is especially useful when driving nuts onto exposed threaded rod or studs where a closed-end driver would be blocked. It is sold individually as a single unit.

Compatibility

Installation Notes

This nut driver is a hand tool and requires no power source or special installation. Always de-energize electrical equipment before working on panels or enclosures where this tool will be used, in accordance with NFPA 70E arc flash and shock hazard protocols. Use the hollow shaft to fully engage threaded fasteners before applying torque to prevent cam-out. Inspect the handle and shaft for cracks or damage before each use.
