The hollow shaft allows the driver to slide over threaded rod or stud ends without bottoming out, giving trades a reliable solution where solid-shaft drivers fail. The hex drive size is 3\/8 inch, the shank measures 3 inches, and the overall tool length is 6.75 inches. The cushion grip handle provides control and reduces hand fatigue during repetitive fastening tasks. This tool is sold individually and weighs 0.2 pounds.\u003c\/p\u003e\u003cp\u003eThe 630-3\/8 is suited for electrical, HVAC, and general mechanical work where 3\/8 inch hex fasteners are common. The hollow shaft design is especially useful when mounting electrical panels, equipment brackets, or conduit supports where long machine screws or all-thread rod is involved. It fits standard residential and light commercial applications where hand-driven nut setting is preferred over impact tools.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHollow shaft passes over long bolts and threaded studs without interference\u003c\/li\u003e\n\u003cli\u003e3\/8 inch hex drive size fits standard hex-head fasteners\u003c\/li\u003e\n\u003cli\u003e3 inch shank length provides reach in recessed or tight spaces\u003c\/li\u003e\n\u003cli\u003e6.75 inch overall length balances reach and control\u003c\/li\u003e\n\u003cli\u003eCushion grip handle reduces hand fatigue during extended use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style hand tool for use with 3\/8 inch hex-head fasteners in electrical, HVAC, and mechanical installation applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis nut driver is a hand tool intended for use by electricians, HVAC technicians, and plumbers working with hex fasteners.
