The WILLIAMS COMFORT PRODUCTS 50671 is a 22-piece, 3/8 inch drive bolt-thru socket set designed for professional trade use in mechanical, HVAC, plumbing, and general maintenance applications. The bolt-thru design allows the socket to pass completely over a threaded fastener or stud, giving technicians access to recessed or extended bolt configurations that standard sockets cannot reach. At 4.25 pounds, this set offers a solid, durable feel suited to repeated daily use on job sites and service calls.
This socket set is well suited for HVAC installers, plumbers, electricians, and general mechanical contractors who routinely encounter varied fastener types during equipment installation and service. The 3/8 inch drive size is a common standard in trade tool kits, offering a balance of torque capacity and maneuverability in tight spaces such as equipment panels, pipe hangers, and electrical enclosures. The 22-piece count provides coverage across a broad range of fastener sizes for most service scenarios.
Designed as a standard 3/8 inch drive socket set compatible with any 3/8 inch drive ratchet, breaker bar, torque wrench, or extension from any major tool manufacturer.
A licensed or journeyman-level technician in any mechanical trade can integrate this socket set into an existing 3/8 inch drive tool kit without modification. Before servicing any equipment, follow lockout/tagout procedures and shut off all power, gas, and water supplies as applicable. Inspect each socket for cracks or deformation before applying torque to avoid fastener damage or socket failure. Store in the provided set organizer to maintain socket accountability on the job site.
