This deep impact socket is crafted from high - quality heat - treated CR - MO. The corrosion - resistant black phosphate surface treatment serves to reduce rust. The 6 - point socket design prevents chamfering and does not slip easily during use. Each socket bears highly visible laser - etched size markings, allowing for better identification even in poorly lit environments.

• This 1/2 - inch socket is crafted from CR - MO material. After undergoing high - temperature forging and heat treatment, it is given a black phosphating treatment. This process endows it with extremely high hardness, durability, and corrosion resistance.
• This socket is designed with a hexagonal opening, conforming to the industry - standard 6 - point configuration. The hexagonal shape provides superior grip on nuts and bolts, minimizing the chance of rounding off the fastener corners.
