Forged from chrome-molybdenum steel with a hardness of up to 54HRC, it has excellent wear resistance and durability and can maintain stable performance in high-pressure, high-torque working environments. The phosphating black treated surface has good adsorption of grease and lubricants, which helps reduce friction and improve working efficiency. The chamfered design makes it easier to insert the socket into the bolt or nut, effectively preventing the drill and fastener from wearing. The pinhole base can provide additional support, making the socket more stable during use and preventing shaking or sliding. The size markings on the product allow you to easily identify the size of the socket and quickly select the appropriate tool for use. Used with ratchet wrenches, open-end wrenches, power impact wrenches, and socket wrenches, it is widely used for the removal and tightening of bolts required for professional automotive mechanical maintenance, daily repairs, equipment installation, and other projects. Before purchasing, please make sure the socket size you choose matches the size of the bolt or nut you need to use.
