The polished chromed surface is smooth, helping to prevent rust and corrosion, thereby extending the tool's lifespan. The socket features a recessed hex design, making it easier for nuts to fit in. The surface is treated with industrial double grooves, increasing friction and providing 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. 45# steel sockets are widely used for installing and removing various structural fasteners. Suitable for automotive repair, DIY handcrafting, construction, and machinery maintenance.
