Proto JN1304RMS Nut Driver Hollow Shaft 9.25 in Oal

Product Description

The PROTO JN1304RMS is a hollow-shaft nut driver built for professional tradespeople who need reliable fastener control in tight or deep-access applications. The hollow shaft design accommodates threaded rod or extended bolt protrusions, allowing the driver to seat fully onto the fastener without bottoming out. At 9.25 inches overall length with a 4-inch blade, this driver provides the reach and leverage needed for HVAC panels, electrical enclosures, and plumbing access work. The ergonomic handle reduces fatigue during repetitive fastening tasks. This driver meets ANSI B107.12 specifications and is backed by a lifetime warranty.

The JN1304RMS is suited for residential and light commercial service work where 13 mm fasteners are common. Typical applications include securing HVAC sheet metal screws and hex-head fasteners on electrical panels, conduit fittings, and equipment housings. The hollow shaft makes it especially practical when working on studs or long bolts where a standard closed-end driver would not fully engage.

Installation Notes

This tool is used by HVAC technicians, electricians, and plumbers for manual fastener driving and removal. No power-down procedure is required for the tool itself, but always de-energize electrical equipment and shut off system power before accessing panels or enclosures. Inspect the driver for wear or damage before each use and do not apply excessive lateral force to the shaft.
