Proto JKB1404RPF Slotted Screwdriver 0.25 in Keystone

Product Description

The PROTO JKB1404RPF is a slotted keystone screwdriver built for trade professionals who need a reliable, precision-ground hand tool for fastener installation and removal. The blade measures 0.25 inches wide and 4 inches long, with an overall length of 8.25 inches for reach in standard access points. A round shank and keystone tip profile provide the blade geometry required for driving slotted fasteners in tight clearances. The ergonomic handle, measuring 4.25 inches in length, is contoured to reduce hand fatigue during extended use. Blade thickness is 0.037 inches, which keeps the tip seated firmly in the fastener slot. This tool weighs 0.2 pounds and fits in a standard tool pouch or kit tray.

This screwdriver is suited for use across HVAC, electrical, plumbing, and general trade applications where slotted fasteners appear on terminal blocks, junction box covers, access panels, equipment cabinets, and control boards. The 4-inch blade length is well matched to standard panel and enclosure depths. Electricians, HVAC technicians, and plumbers will find the keystone tip geometry appropriate for the flathead screws common in low-voltage control wiring and mechanical equipment installations.

Installation Notes

Hand tools require no installation but should be inspected before each use for blade damage, tip rounding, or handle cracks that could compromise fastener engagement or user safety. When driving slotted fasteners on live electrical panels or control boards, de-energize the circuit and follow applicable NEC lockout/tagout procedures before work begins. The round shank on this driver accepts an open-end wrench for additional torque on stubborn fasteners — apply controlled force to avoid cam-out or fastener damage. Do not use as a pry bar or chisel; use only for its intended slotted fastener driving application.
