Klein Tools 630-1/4 Nut Driver 1/4 Inch Hex Hollow Shaft

Product Description

The KLEIN TOOLS 630-1/4 is a hollow-shaft nut driver designed for fastening and loosening hex nuts in trade applications. The hollow shaft design allows the driver to slide over long bolts and threaded studs without bottoming out, making it practical for electrical panel work, HVAC equipment installation, and light commercial assembly. The hex drive size is 1/4 inch, with a 3-inch shank and an overall length of 6.75 inches. The cushion grip handle provides a firm, comfortable hold during extended use. Licensed electricians, HVAC technicians, and plumbers commonly keep this size in their hand-tool kits.

This nut driver suits residential and light commercial service work where 1/4 inch hex fasteners are standard. Common applications include securing electrical enclosure hardware, mounting HVAC components, and assembling sheet metal equipment. The hollow shaft is particularly useful when working with machine screws and long studs where a solid-shaft driver would bind before fully seating the nut.
