The WILLIAMS JHW38936 is a 10-piece metric hex bit socket set built for heavy-duty fastener work requiring a 3/4 inch drive. Manufactured from vanadium steel, these sockets deliver the toughness needed for high-torque applications common in mechanical, HVAC equipment assembly, and industrial service environments. The set covers metric hex sizes from 10 millimeters through 32 millimeters, giving technicians a wide range without carrying multiple individual sockets. Each socket measures 3.5 inches in overall length. The set ships non-insulated and is intended for use with standard 3/4 inch drive ratchets, breaker bars, or torque wrenches.
This socket set is suited for commercial and industrial applications where large metric hex fasteners are common, including equipment installation, pump and motor service, chiller and rooftop unit mechanical work, and general mechanical assembly. Trade professionals working on large HVAC equipment, compressors, and structural hardware will find the 10-32mm range especially practical. The 3/4 inch drive matches the heavy-duty drive tools already standard in most commercial service vans and shop setups.
Designed for use with standard 3/4 inch drive tools; fits any 3/4 inch drive ratchet, breaker bar, or torque wrench accepting metric hex bit sockets.
Installation and use should be performed by qualified mechanical or service technicians familiar with high-torque fastener procedures. Always ensure the drive tool and socket are fully engaged before applying torque to avoid rounding fasteners or causing socket ejection. Inspect sockets for cracks or wear before each use. Follow applicable equipment service manuals and safety guidelines when working on pressurized or energized systems.
