Williams Comfort Products 31904 Hex Bit Socket Set 7 Pc

Product Description

The WILLIAMS COMFORT PRODUCTS 31904 is a 7-piece hex bit socket set built for professional tradespeople who need reliable fastening capability on the job. Driven by a 3/8 inch drive, this set covers a range of hex bit sizes suited to mechanical assembly, equipment service, and component installation across HVAC, plumbing, and general mechanical trade work. The set is compact enough for a tool bag yet comprehensive enough to handle the fastener variety encountered on most service calls. At 1.019 pounds, it is lightweight without sacrificing the durability expected from a professional-grade hand tool set.

This hex bit socket set is appropriate for residential and light commercial service environments where a 3/8 inch drive ratchet or breaker bar is the standard tool. It is well suited for tasks involving set screws, cap screws, and hex-head fasteners common in HVAC equipment panels, pump housings, and electrical enclosures. Technicians working in confined spaces will benefit from the socket format, which allows for better torque application compared to standard L-keys in restricted access areas.

Key Features

• 7-piece set provides coverage across common hex bit sizes for varied fastener applications
• 3/8 inch drive interface is compatible with standard ratchets, extensions, and torque wrenches
• Compact socket format improves access and torque leverage in tight spaces
• Lightweight at 1.019 pounds for easy transport in a service bag or tool kit
• Sold as a complete set for consistent tool availability on multi-fastener jobs

Compatibility

Designed for use with any standard 3/8 inch drive ratchet, torque wrench, or breaker bar commonly used in HVAC, plumbing, electrical, and general mechanical service applications.

Installation Notes

This set is intended for use by licensed tradespeople and experienced service technicians. Always ensure the correct hex bit size is seated fully before applying torque to avoid fastener damage or bit slippage. When used on equipment service, de-energize electrical systems and shut off fluid or gas supply before accessing fastener locations. Follow applicable codes and equipment manufacturer guidelines for fastener torque requirements.
