The WILLIAMS COMFORT PRODUCTS JHW35071 is a 4 MM hex socket bit designed for use with 1/4 inch drive tools. It features a 15/32 inch outer diameter and a high-polish chrome finish that resists corrosion and wipes clean between uses. This is a metric hex bit suited for fastener work in HVAC, plumbing, and mechanical service applications where a compact, precision hex driver is required. It is sold individually and is sized for environments where space constraints demand a smaller drive format.
This socket bit is intended for use in residential and light commercial service settings where 4 MM metric hex fasteners are common. Typical applications include equipment panel removal, bracket fastening, and component service on HVAC units, pumps, and mechanical assemblies. The 1/4 inch drive format makes it compatible with standard ratchets, extensions, and bit holders found in most trade toolkits.
Designed as an OEM-style replacement hex socket bit for use with standard 1/4 inch drive ratchets, bit holders, and extension bars in trade service applications.
This socket bit is used by HVAC technicians, plumbers, and general mechanical service professionals. Ensure the drive tool is not under load before attaching or removing the bit. Use appropriate personal protective equipment when working near energized or pressurized equipment. Verify the fastener size matches the 4 MM hex specification before applying torque to avoid fastener damage.
