Specification Brand : HARFINGTON BulletPoint1 : Size - 6 Point Socket Size: 1/2" Drive, 18mm; Total Length: 39 mm / 1.5"; Package includes: 3 x socket BulletPoint2 : Material - The socket is made from heat-treated 45# steel, which increases torque and stability and reduces deformation. Mirror-polished chrome surface is smooth, helping to prevent rust and corrosion, thereby extending the tool's lifespan. BulletPoint3 : Advantage - The recessed hexagon design makes it easier to load the nut while also firmly gripping the fastener, minimizing the risk of rounding and providing a comfortable grip to turn the fastener even when space is tight. The surface is treated with industrial double grooves, increasing friction and providing better anti-slip properties. BulletPoint4 : Quick Switching - The specifications of the socket are engraved on the surface, making them clearly visible for quickly switching between different socket sizes during work. BulletPoint5 : Application - 45# steel sockets are widely used for installing and removing various structural fasteners. Suitable for automotive repair, DIY handcrafting, construction, and machinery maintenance.
