The Makita 1/2″ Square Drive Impact Socket is a tough and reliable tool designed for heavy-duty fastening jobs. Made from durable chrome-molybdenum steel, this impact socket is built to handle the high torque produced by electric and pneumatic impact wrenches. This socket fits tightly onto nuts and bolts, allowing for strong torque transfer while helping to prevent slipping or rounding off edges. Its compact yet durable build offers easy access to fasteners in tighter spaces without compromising strength. The socket features a built-in pin and O-ring retention system to keep it securely attached to your tool during use, which helps prevent accidental drops—especially useful when working overhead or in awkward angles. Its thick walls are designed to absorb the stress of repeated impacts, while the corrosion-resistant finish ensures long-term protection against rust and wear.
