Specification Brand : HARFINGTON BulletPoint1 : Size - Drive: 3/8"; Socket Specifications: E10; Total Length: 30mm / 1.2"; Package includes: 4 x External Torx Socket. The specifications of the socket are visible and engraved on the surface. You can quickly switch between different socket sizes to improve work efficiency. BulletPoint2 : Material - The E-type plum star female socket is made of high-hardness chrome vanadium steel (50BV30), which has good strength and wear resistance, is not easy to deform or damage, and is suitable for high-torque working environments. The polished chrome plating has a smooth surface, which helps prevent rust and corrosion and improves the appearance and texture of the socket, thereby extending the service life of the tool. BulletPoint3 : Feature - Female E torx star socket adopts a 6-point spline structure, which can better insert smoothly onto fasteners with precision chamfered ends, providing a stronger grip when in use, preventing the fastener from becoming round, and not easily slipping, improving operational safety and work efficiency. BulletPoint4 : Application - E-Torx sockets are designed to effectively tighten or remove Torx screws and bolts when repairing the body, interior frames, and electrical sensors, suitable for automobiles, motorcycles, bicycles, lawn equipment, professional machinery, home maintenance, DIY crafts, etc. BulletPoint5 : Note - Make sure the selected socket size matches the head of the screw or nut to avoid slippage or damage due to size mismatch; when using a socket tool to tighten or remove screws, apply uniform and appropriate force to avoid excessive force that may cause damage to the socket or thread.
