Proto JK3812RF Slotted Screwdriver 3/8 in Keystone Tip

Product Description

The PROTO JK3812RF is a heavy-duty slotted screwdriver built for professional tradespeople who need reach and control on fasteners in deep or recessed locations. The keystone-tip blade measures 3/8 inch wide and 12 inches long, giving it the extended reach required for electrical panels, HVAC equipment cabinets, and mechanical assemblies. Overall length is 16-3/4 inches. The round shank allows a wrench to be applied for extra torque when driving stubborn fasteners. An ergonomic handle, measuring 4-3/4 inches in length, reduces hand fatigue during sustained use.

This screwdriver is suited for electricians, HVAC technicians, plumbers, and general maintenance professionals who regularly work inside deep enclosures or equipment cabinets. The extended blade length makes it well-suited for reaching fasteners that shorter screwdrivers cannot access. It is a single-piece hand tool requiring no power source, making it appropriate for job sites where power tools are impractical or restricted. The keystone tip is a standard profile compatible with a wide range of slotted fastener heads found in trade and industrial applications.

Installation Notes

This tool is intended for use by qualified tradespeople familiar with hand tool safety practices. Always ensure the tip is fully seated in the fastener slot before applying torque to prevent tip slippage or fastener damage. When using the round shank wrench feature, apply steady controlled force and avoid exceeding the fastener or material rating. Inspect the blade tip for wear or damage before each use and replace if the tip is chipped or rounded.
