The WILLIAMS COMFORT PRODUCTS JHW35419 is a metric deep impact socket designed for use with 3/8 inch drive pneumatic and electric impact wrenches. Built for professional-grade fastener work, this socket features lobular internal openings that increase turning force while reducing fastener deformation under high torque. The socket measures 19MM in drive size with an overall length of 2.5 inches, making it well suited for recessed or deep-set fastener applications. Specially heat treated for impact service, it is engineered to withstand the stress cycles associated with repeated pneumatic and electric impact use across demanding trade environments.
This socket is a practical addition to any service kit where metric fasteners are encountered in tight or deep access points. Its 2.5 inch overall length provides the clearance needed to reach fasteners seated below surfaces. Suitable for use across automotive, mechanical, HVAC equipment servicing, and general industrial applications, the JHW35419 works with standard 3/8 inch drive impact wrenches. The metric 19MM size covers a common fastener specification found in equipment manufactured to metric standards.
Designed as a direct-fit deep impact socket for 3/8 inch drive impact wrenches and ratchets requiring a metric 19MM socket.
Install and remove this socket only when the tool is powered down or the air supply is disconnected. Confirm the socket is fully seated on the drive before applying torque. Inspect the socket for cracks or deformation before each use, and remove it from service if damage is found. Always use impact-rated sockets with impact wrenches — do not substitute standard chrome sockets in impact applications.
