The WILLIAMS COMFORT PRODUCTS JHW36817 is a 17 MM metric impact socket designed for use with 3/8 inch drive pneumatic and electric impact wrenches. Built for trade professionals who need reliable fastener engagement under high-torque conditions, this socket features lobular openings that grip 6-point fasteners with greater turning power while reducing the risk of fastener deformation. Specially heat treated for impact use, the JHW36817 delivers long service life and structural durability in demanding shop and field environments. The drive end includes a pin retention hole and groove for secure tool attachment during operation.
This socket is suited for automotive, mechanical, and industrial applications where metric fasteners are standard. The universal impact design makes it compatible with both pneumatic air tools and electric impact wrenches, giving technicians flexibility across different tool setups. With a compact overall length of 2.7 inches and a width of 1 inch, it fits into tighter spaces where larger sockets cannot reach. Each unit is sold individually, making it practical for adding a single size to an existing socket set or replacing a worn piece.
Designed as an OEM-style replacement or add-on impact socket for use with standard 3/8 inch drive pneumatic and electric impact tools in metric applications.
Installation and use should be performed by qualified mechanics or tradespeople familiar with impact tooling. Always ensure the socket is fully seated and the retention pin is engaged before applying torque. Do not use impact sockets with standard hand-drive ratchets, as the torque loads from impact tools exceed the design tolerances of non-impact hand tools. Inspect the socket for cracks or wear before each use and replace if damage is found.
