The WILLIAMS COMFORT PRODUCTS JHW12M-612 is a 12 MM metric deep impact socket with a 3/8 inch drive and an overall length of 2 1/8 inches. Built for use with pneumatic and electric impact wrenches, it features SUPERTORQUE lobular openings that deliver greater turning power while protecting fastener heads from deformation. The socket is specially heat treated for impact use, providing long-term durability and safe operation under high-torque conditions. This is a professional-grade hand tool designed for technicians who work with metric fasteners in demanding service environments.
This deep impact socket is suited for automotive, HVAC, plumbing, and general mechanical service work where metric fasteners and impact tools are standard. The 12 MM size and 3/8 inch drive make it a common fit for engine components, equipment panels, and mechanical assemblies. Its deep profile allows it to seat fully on recessed or extended fasteners that a standard-depth socket cannot reach. Technicians working in production, fleet, or field service environments will find this socket a reliable addition to their impact drive set.
Designed as an OEM-style deep impact socket for use with standard 3/8 inch drive pneumatic and electric impact wrenches accepting 12 MM metric sockets.
This socket is installed by a mechanic or service technician using a 3/8 inch drive impact wrench or ratchet. Ensure the drive tool is rated for impact use before attaching this socket. Inspect the socket for cracks or wear before each use, and never use impact sockets with standard hand-ratchet extensions not rated for impact loads.
