Proto JK51608RF Slotted Screwdriver 5/16 in Keystone

Product Description

The PROTO JK51608RF is a slotted keystone screwdriver built for heavy-duty trade use. The blade measures 5/16 inch wide and 8 inches long, with a total overall length of 12-1/2 inches. The round shank is paired with an ergonomic handle that spans 4-1/2 inches, giving the user firm control during high-torque fastening. The keystone tip profile is suited for larger slotted fasteners found in electrical panels, HVAC equipment, and mechanical assemblies. This screwdriver is a standard hand tool carried by electricians, HVAC technicians, and plumbers for service and installation work.

The JK51608RF is appropriate for residential and commercial service applications where a longer-reach slotted screwdriver is required. The 8-inch blade provides access to recessed fasteners in junction boxes, control panels, and equipment cabinets. The ergonomic handle reduces fatigue during repeated fastening tasks on the job site or in the field.

Installation Notes

This screwdriver is used by electricians, HVAC technicians, and plumbers as a standard hand tool. Always de-energize electrical equipment and follow applicable NEC guidelines before working inside panels or enclosures. Inspect the tip for wear or damage before use, as a worn tip can slip and damage fastener heads or cause injury. Use the round shank with a wrench only when the handle design and fastener require additional torque.
