Description
?? Product Overview
Drive Size: ½? square drive — built to fit common impact wrenches and ratchets
Bit Type: Hexagon (Allen) bit — fits 5/16? hex fasteners
Length: Typically around 55?mm, giving balanced reach and control
Material & Finish: Machined from chrome-molybdenum steel with a black phosphate finish — engineered for high torque and corrosion protection
Construction: One-piece design — stronger than two-piece bits, ideal for repeated impact use
?? Key Benefits
Impact-Rated Durability: Made from robust Cr-Mo steel with thick walls, this bit resists the shock loading of impact wrenches better than standard steel bits.
Tight Fastener Access: With a compact ~55?mm length, it strikes a good balance—long enough to reach recessed bolts, yet short enough to stay stable under torque.
Precise Fit & Strength: Hex profile provides strong surface contact with fastener flats, reducing stripping and enhancing torque transfer.
