Socket 3/8’Dr 20Mm 12Pt Crv

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.
