Proto JKB51606RPF Slotted Screwdriver 5/16 in Keystone

Product Description

The PROTO JKB51606RPF is a slotted keystone screwdriver built for professional tradespeople who need a reliable, full-size flathead driver for heavy-duty fastening tasks. The blade measures 5/16 inch wide and 6 inches long, with an overall length of 10-1/2 inches. The round shank is designed for use with a wrench when additional torque is needed. An ergonomic handle with a 4-1/2 inch length reduces hand fatigue during extended use. This driver is appropriate for electrical, HVAC, plumbing, and general mechanical work where slotted fasteners are encountered.

This screwdriver is suited for residential and commercial service work. It fits standard slotted screw heads in the keystone tip style, which is a flat, slightly tapered profile commonly found on terminal screws, junction box hardware, electrical panels, and equipment covers. Electricians, HVAC technicians, and plumbers reach for a driver in this size range when working on panel knockouts, cover plates, and field-wiring connections that require a wide, sturdy blade.

Installation Notes

A licensed electrician or qualified tradesperson should de-energize and lock out equipment before using any screwdriver near live terminals or energized components, per applicable NEC and OSHA lockout/tagout requirements. Ensure the blade width and thickness match the screw slot before applying torque to avoid damaging the fastener head or the work surface. When using the round shank with a wrench for added leverage, apply controlled force to prevent stripping or shearing smaller fasteners.
