Proto JN1204RS Nut Driver 1/2 Inch Hollow Shaft 9.25 Inch Oal

Product Description

The PROTO JN1204RS is a hollow-shaft nut driver built for professional tradespeople who need a reliable hand tool for driving hex fasteners in tight or deep-reach applications. The hollow shaft allows the driver to seat over long bolt or stud ends that would otherwise block a standard closed-shaft tool. The 1/2-inch drive size handles common hex fasteners found on HVAC equipment panels, electrical enclosures, and plumbing fixture hardware. At 9.25 inches overall length with a 4-inch blade, the JN1204RS gives techs the reach needed to work in confined spaces without sacrificing control. The ergonomic handle reduces fatigue during repetitive fastening tasks.

This nut driver is suited for residential and light commercial service work across HVAC, electrical, and plumbing trades. It is a standard single-piece hand tool that ships in a pouch and is appropriate for technicians who need a dedicated 1/2-inch driver in their kit. The hollow shaft design makes it especially practical when working with machine screws or bolts that extend beyond the nut face, a common condition inside sheet metal equipment enclosures and electrical panels.

Installation Notes

De-energize all electrical equipment and shut off any relevant services before working inside panels or enclosures where this tool will be used. This is a hand tool requiring no special installation procedure, but technicians should verify fastener size before applying torque to avoid rounding hex heads. Keep the shaft clear of debris to maintain full hollow-shaft clearance during use.
