Klein Tools 618-5/16M Magnetic Nut Driver 5/16 in 18 in

Product Description

The KLEIN TOOLS 618-5/16M is a magnetic tip nut driver built for professional electrical and mechanical work. The 5/16-inch drive size handles the fasteners most commonly found in electrical panels, enclosures, and equipment installations. The 18-inch hollow shaft provides extended reach into deep cavities and conduit bodies where standard-length drivers cannot reach. The magnetic tip seats and holds the nut securely, reducing the chance of dropping hardware in confined spaces. This driver is a standard tool for licensed electricians, HVAC technicians, and industrial maintenance crews who work in tight or deep installations daily.

This nut driver is suited for residential and commercial electrical work, panel assembly, HVAC equipment service, and general mechanical installations where a 5/16-inch fastener and extended reach are required. The hollow shaft design accommodates longer bolt or stud protrusions, making it practical for terminal work and equipment mounting tasks. It is sold individually, with a minimum order quantity of 3 units per pack.
