Wiha 28563 T7 Torx Power Screwdriver Bit 0.16 in Hex

Product Description

The WIHA 28563 is a T7 Torx power screwdriver bit designed for use with power drivers and impact-rated bit holders in professional trade and industrial fastening applications. Constructed from steel, the bit features a 0.16 inch (0.1563 inch nominal) hex shank that fits standard 1/4 inch hex drive power tools. The T7 Torx tip engages small Torx fasteners precisely, reducing cam-out and wear during high-cycle use. This is a single-piece bit suited for HVAC technicians, electricians, and service pros working with equipment panels, control boards, and enclosures that use small Torx fasteners.

The WIHA 28563 is commonly used in light-duty fastening tasks on residential and commercial equipment where small T7 Torx screws are specified. Typical applications include securing control board covers, terminal enclosures, and panel hardware on HVAC units, electrical equipment, and similar trade installations. The compact T7 profile handles the smallest Torx sizes found on equipment access panels and printed circuit board mounting hardware.
