The WIHA 70319 is a T20 Torx power screwdriver bit designed for use with power drivers and impact-rated bit holders equipped with a 1/4 inch hex shank. The bit measures 3.5 inches in overall length, giving technicians added reach in confined or deep-access fastening situations. Each package contains two bits, making it a practical option for service kits and tool bags. HVAC technicians, electricians, plumbers, and general trade professionals commonly use T20 Torx bits when servicing equipment panels, control board enclosures, and cabinet fasteners that require a Torx drive profile.
This bit is suited for residential and light commercial applications where T20 Torx fasteners are specified. It is compatible with any standard 1/4 inch hex bit holder, quick-change chuck, or right-angle adapter. The 3.5 inch length makes it well suited for reaching fasteners recessed behind panels or inside equipment enclosures without requiring an extension. The two-piece pack supports having a backup on hand during service calls.
Designed for use with any power driver, drill, or bit holder accepting a standard 1/4 inch hex shank bit.
Install and remove using a power driver or drill fitted with a 1/4 inch hex chuck or quick-change holder. Ensure the bit is fully seated in the holder before applying torque to prevent cam-out or fastener damage. When servicing energized equipment panels or control enclosures, de-energize and lock out the circuit per applicable NEC or equipment-specific safety procedures before accessing fasteners.
