Proto JN1104RMS Hollow Shaft Nut Driver 11 Mm

Product Description

The PROTO JN1104RMS is a hollow shaft nut driver built for professional use in HVAC, electrical, and mechanical service work. The hollow shaft design allows the driver to seat over long fasteners, threaded rod, and protruding studs that a solid shaft tool cannot clear. The 11 mm drive size handles common hex fasteners found in control panels, equipment cabinets, and access covers. The ergonomic handle is designed to reduce hand fatigue during repetitive tightening tasks. Overall length is 9.25 inches with a blade length of 4 inches. This tool meets ANSI Spec B107.12 and carries a lifetime warranty from PROTO.

The JN1104RMS is suited for residential and commercial service environments where technicians need reliable hand tools for panel work, conduit fittings, and equipment assembly. The hollow shaft is particularly useful in electrical and HVAC applications where fasteners pass through terminal blocks or threaded standoffs. It is packaged in a pouch and sold individually, making it a practical addition to a service tech kit or a replacement for a worn driver in an existing set.

Always de-energize electrical panels and equipment before working on fasteners near live components. Inspect the blade tip for wear before use to ensure proper fastener engagement and avoid rounding hardware. This tool is intended for hand-torque applications only and should not be used with power drive adapters.
