Socket 3/8'dr 20mm 12pt Crv

20mm 12-Point Socket Drive Size: 3 / 8 " Drive Type: Square Drive The 20mm 12-point socket is a heavy-duty specialty tool designed for those larger, high-torque fasteners that require a precision fit within a 3/8' drive system. This size is increasingly common in modern automotive applications, particularly for crankshaft bolts, transmission housings, and specialized suspension components. By utilizing the 3/8' drive format, this socket allows you to apply significant rotational force while maintaining a more compact profile than larger drive sizes, making it easier to maneuver in dense mechanical assemblies. The 12-point (double-hex) geometry is engineered for maximum versatility in restricted workspaces. By doubling the number of possible engagement angles, it allows you to seat the tool onto a 20mm fastener with only 30 degrees of rotation. This is a critical advantage when working in the undercarriages of vehicles or behind heavy machinery where your swing arc is obstructed, ensuring you can find a solid grip and maintain productivity even in the tightest spots. Constructed from premium Chrome Vanadium (Cr-V) steel, this socket is built to endure the rigors of professional use. The high-performance alloy is heat-treated to ensure the walls remain rigid under heavy stress, preventing the socket from spreading or failing during high-torque applications. To ensure a long service life in demanding shop environments, it is finished with a mirror-polished chrome coating that resists rust, corrosion, and the buildup of grease and grime. Inside, the socket is precision-machined to provide an exacting, high-tolerance fit on 20mm fasteners. This meticulous broaching ensures that pressure is distributed evenly across the flat sides of the bolt head, rather than the corners, which dramatically reduces the risk of rounding off your hardware. Whether you are a professional technician or a dedicated home restorer, this 20mm socket provides the professional-grade reliability and precision necessary for high-stakes repairs.
