Klein Tools bd284 Keystone Screwdriver 1/4 in Square Shank

Product Description

The KLEIN TOOLS bd284 is a 1/4-inch keystone-tip flathead screwdriver built for trade professionals who demand reliable hand tools on the job. The shank is square, measuring 4 inches in length, which allows a wrench to be applied directly to the shaft for extra turning force when fasteners are stubborn. The blade tip is forged and precision-ground with square edges to fit screw openings securely, resisting cam-out and slippage under load. The shaft is made from tempered steel and features an integral flange that locks it firmly into the handle, creating a torque-proof anchor. Overall length is 8.5 inches. Total weight is 0.25 pounds.

This screwdriver is suited for residential and commercial electrical, mechanical, and general trade work where a standard keystone flathead driver is required. The 4-inch square shank design is particularly useful in tight situations where additional torque is needed and a wrench can be positioned on the shank. The yellow plastic handle provides a clear visual indicator in a tool bag or on a workbench. Licensed electricians, HVAC technicians, plumbers, and general contractors commonly carry this style of driver as a core hand tool.
