Ivy Classic - Square Power Bit, 2 inch #3

Built for heavy Robertson screws, this 2" SQ3 power bit delivers rock-solid engagement and serious torque without cam-out. A precision-machined square tip teams with a heat-treated S2 tool-steel core for long life in drills and impact drivers. The 2" length clears chuck jaws for better sightlines and control, while the 1/4" hex shank locks securely into standard bit holders and magnetic sleeves—perfect for decking, framing connectors, and tough assembly work.

Key Features
