Williams Comfort Products MMD-604 Deep Socket 6-point 4MM

Product Description

The Williams Comfort Products MMD-604 is a 1/4-inch drive deep socket with a 6-point design sized for 4MM fasteners. Built for professional use, this deep socket provides the added clearance needed to reach recessed or extended bolt heads that standard-depth sockets cannot access. The 6-point configuration maximizes contact with fastener flats, reducing the risk of rounding under torque. Technicians across HVAC, plumbing, and general mechanical service rely on deep sockets like this for equipment access panels, motor mounts, and component fasteners in tight spaces.

This socket is suited for service work where a 1/4-inch drive ratchet or extension bar is the appropriate tool, particularly in confined equipment compartments. The 4MM metric sizing makes it a practical addition to any professional socket set used on equipment with metric fastener specifications. It is sold individually, making it a convenient replacement or addition for a specific drive size.

Installation Notes

This socket is installed by hand tool technicians and service professionals. Always ensure the socket is fully seated on the fastener before applying torque to avoid slippage.
