Apex 445-3X Slotted Screwdriver Bit 1/4 Inch Drive

Product Description

The APEX 445-3X is a 1/4-inch drive slotted screwdriver insert bit designed for use with standard 1/4-inch hex drive power tools and hand drivers. The blade measures 1/4 inch wide by 0.042 inch thick, and the overall length is 1 inch, consistent with standard insert bit sizing. Constructed from steel, this bit delivers the rigidity required for repeated fastening tasks in HVAC, electrical, and mechanical service work. It is sized for common slotted fasteners found on terminal covers, junction boxes, and equipment panels.

This insert bit is suited for residential and light commercial service applications where technicians encounter slotted screw fasteners during equipment installation, maintenance, or panel access. Its 1/4-inch hex shank fits directly into impact drivers, electric screwdrivers, and bit holders used daily by HVAC technicians, electricians, and plumbers on the job site or in the shop.

Installation Notes

Insert bits are installed and removed by hand into any compatible 1/4-inch hex bit holder or quick-change chuck — no tools required for the bit itself. Ensure the fastener slot width matches the blade width before applying torque to avoid cam-out or fastener damage. When servicing energized electrical or HVAC equipment, follow applicable NEC or equipment lockout/tagout procedures before accessing fasteners on live panels or terminal covers.
