Proto JK1404RF Slotted Screwdriver 1/4 in Keystone

Product Description

The PROTO JK1404RF is a slotted keystone screwdriver built for professional tradespeople who need a reliable, well-balanced hand tool for fastening and removal tasks. The blade is 4 inches long with a 1/4 inch width and a thickness of 0.037 inches, ground to a keystone profile that resists cam-out under torque. The round shank allows a wrench to be applied at the shank for additional turning force when needed. Overall length is 8-1/4 inches. The ergonomic handle measures 4-1/4 inches and is designed to reduce hand fatigue during extended use. This screwdriver is suited for electricians, HVAC technicians, plumbers, and general service pros working with slotted fasteners in panels, equipment enclosures, and mechanical assemblies.

The JK1404RF is appropriate for residential and light commercial service work wherever 1/4 inch slotted fasteners are encountered. Typical applications include terminal screws in electrical panels, cover plate fasteners, equipment service panels, and general maintenance tasks. The keystone tip geometry is suited for medium to large slotted fasteners and provides good surface contact across the slot. The compact 4 inch blade length allows access in moderately confined spaces without sacrificing leverage.

Installation Notes

De-energize and lock out electrical equipment before using any screwdriver near live terminals or panel components, in accordance with applicable NFPA 70E and NEC guidelines. Inspect the blade tip before use and replace the tool if the tip is chipped, rounded, or deformed, as a damaged tip increases the risk of fastener damage and slippage. Apply firm, steady axial pressure while turning to keep the blade seated in the slot. Do not use this screwdriver as a pry bar or chisel.
