The WILLIAMS COMFORT PRODUCTS JHW35408 is a metric deep impact socket designed for heavy-duty fastening applications in the trades. Built with a 3/8 inch drive and sized at 8 MM, it delivers reliable torque transfer through a SUPERTORQUE lobular opening profile that applies force to the flats of the fastener rather than the corners. This reduces the risk of rounding or deforming fasteners under high-torque conditions. The socket measures 2.5 inches overall length and has been specially heat treated for impact use, making it suitable for both pneumatic and electric impact wrenches. Licensed trades professionals working in mechanical, HVAC, plumbing, and electrical service will find this socket a practical addition to their impact drive sets.
This deep impact socket is appropriate for residential and commercial service work where metric fasteners are common, including equipment installation, panel work, mechanical system assembly, and general maintenance tasks. The deep profile accommodates longer bolt shanks and recessed fastener heads that standard-depth sockets cannot reach. It is sold individually and sized for 8 MM fasteners on a 3/8 inch drive.
Designed as an OEM-style metric deep impact socket for use with 3/8 inch drive pneumatic and electric impact wrenches on 8 MM fasteners.
Install and remove this socket with the impact wrench powered down or the air supply disconnected before swapping drive accessories. Confirm the socket seats fully and locks onto the drive anvil before applying torque. Inspect the socket for cracks or deformation before each use, and do not use adapters that exceed the rated drive size, as this can compromise safety and shorten tool life.
