Proto JN0704RMS Hollow Shaft Nut Driver 9 Inches Oal

Product Description

The PROTO JN0704RMS is a hollow shaft nut driver designed for fastening and loosening hex nuts in confined or deep-reach applications. The hollow shaft design allows the driver to pass over threaded rod or extended bolt ends, making it well suited for electrical panel work, HVAC equipment assembly, and plumbing fixture installation. The tool has a 7.00 mm drive size, a 4-inch blade length, and a 9-inch overall length. The ergonomic handle provides grip control during repeated torque applications. It meets ANSI specification B107.12 and carries a lifetime warranty.

This nut driver is used across trade applications where hex fasteners must be driven in tight or deep clearance areas. Electricians commonly reach for hollow shaft drivers when working around threaded conduit stubs or panel studs. HVAC technicians use them during equipment assembly and service where standard solid-shaft drivers cannot seat fully. The 7.00 mm size fits metric fasteners common on imported HVAC, refrigeration, and electrical components.

Installation Notes

Installation of this tool requires no special setup, but always de-energize electrical panels and equipment before driving fasteners in live environments per NEC guidelines. Inspect the blade and handle for wear or damage before each use. Do not apply supplemental leverage to the handle, as this can damage the driver and fastener head.
