Proto JKB3808RPF Slotted Screwdriver 3/8 in Keystone

Product Description

The PROTO JKB3808RPF is a heavy-duty slotted screwdriver built for trade professionals who need a reliable, full-size flat-blade tool in the field or shop. The keystone-style blade measures 3/8 inch wide and 8 inches long, with an overall length of 12-3/4 inches that gives the user plenty of leverage on stubborn fasteners. The round shank is designed to transfer torque cleanly from the ergonomic handle down to the blade tip. The handle extends 4-3/4 inches and is shaped to reduce hand fatigue during extended use. Weighing in at 0.55 pounds, this screwdriver is a solid, balanced tool suited for daily service work.

This slotted screwdriver is appropriate for residential and commercial service applications across HVAC, electrical, plumbing, and general mechanical trades. It is well suited for terminal screw connections, panel access hardware, junction box covers, and equipment fasteners encountered on typical service calls. The keystone blade profile handles both standard and slightly oversized slotted fastener heads, making it a versatile addition to any service technician's toolkit.

Installation Notes

Always de-energize and lock out electrical equipment before using any screwdriver near live terminals or panels, following applicable NEC guidelines. Inspect the blade tip before use and replace the tool if the tip is chipped, rounded, or mushroomed, as a damaged tip can slip and damage fastener heads or cause injury. Match the blade width to the fastener slot as closely as possible to avoid cam-out. The round shank on this screwdriver is compatible with an open-end or adjustable wrench for added torque on tight fasteners.
