Wiha 70225 Square 2 Power Screwdriver Bit 1/4 Inch Hex

Product Description

The WIHA 70225 is a Number 2 Square drive power screwdriver bit designed for use with power tools and impact-rated drivers that accept a 1/4 inch hex shank. Each bit measures 2 inches in overall length and ships in a two-piece pack, giving technicians a ready backup on the job. The 1/4 inch hex drive seats securely in standard quick-change chucks, reducing slippage and cam-out during high-torque driving. This bit is suited for electricians, HVAC technicians, plumbers, and general trade professionals who regularly drive Square drive fasteners on panels, junction boxes, equipment access covers, and fixture mounting hardware.

The Number 2 Square point size is one of the most common drive configurations found on sheet metal screws, wood screws, and equipment fasteners throughout residential and commercial trade work. These bits are intended for power tool use and hold up to the rotational demands of cordless drivers and drill-drivers. The 2-inch length provides clearance for recessed fastener locations without requiring an extension. The two-piece pack quantity supports tool belt pouches and service van bit organizers where keeping a spare is standard practice.

Installation Notes

Insert the 1/4 inch hex shank fully into the quick-change chuck before driving to ensure proper seating and prevent bit ejection. Electricians and HVAC technicians should confirm the fastener drive size matches the Number 2 Square point before applying power to avoid fastener head damage. When driving into energized equipment enclosures, de-energize and lock out the circuit per NFPA 70E requirements before beginning work. Inspect bits regularly for tip wear, as a worn tip increases cam-out risk and can strip fastener heads.
