The socket is made from heat-treated 45# steel, which increases torque and stability and reduces deformation. The polished chromed surface is smooth, helping to prevent rust and corrosion, thereby extending the tool's lifespan. The recessed 12-point design makes loading the nut easier while firmly gripping a ratchet or extension bar, minimizing the risk of rounding and providing a comfortable grip to turn the fastener even when space is tight. Ball ball-bearing recess on the female end increases friction and provides better anti-slip properties. The specifications of the socket are engraved on the surface, making them clearly visible for quickly switching between different socket sizes during work, improving work efficiency. 45# steel sockets are widely used for installing and removing various structural fasteners. Suitable for automotive repair, DIY handcrafting, construction, and machinery maintenance.
