The WILLIAMS COMFORT PRODUCTS JHW12M-619 is a 19 MM metric deep impact socket designed for use with 3/8 inch drive pneumatic and electric impact wrenches. It features SUPERTORQUE lobular openings that increase turning power while reducing the risk of fastener deformation. The socket is specially heat treated for impact use, delivering long service life and structural integrity under repeated high-torque cycles. At 2.625 inches overall length, it provides the reach needed for recessed or countersunk fasteners in tight working positions. Suitable for professional trades applications requiring reliable metric deep-drive fastening.
This socket is suited for mechanical, HVAC, plumbing, and electrical trade work where metric fasteners are common. The deep profile accommodates extended bolt threads and stud-mounted hardware that standard-depth sockets cannot fully seat on. It is compatible with 3/8 inch drive impact wrenches and ratchets used in both shop and field service settings. Its heat-treated construction makes it appropriate for high-cycle impact use rather than hand-torque-only applications.
Designed as an OEM-style deep impact socket for use with standard 3/8 inch drive impact wrenches and ratchets in metric fastening applications.
This socket is intended for use by qualified trade professionals working with impact wrenches or drive ratchets. Always ensure the drive tool is powered down or the air supply is disconnected before changing sockets. Verify the socket is fully seated on the drive square and fastener before applying torque. Do not use impact sockets on torque-sensitive assemblies unless the torque output is controlled by the drive tool.
