The WILLIAMS COMFORT PRODUCTS 35210-TH is a 1/2-inch drive hex bit socket sized at 5/16 inch. It is a hand tool accessory used with 1/2-inch drive ratchets and breaker bars to drive internal hex fasteners. HVAC technicians, plumbers, and electricians reach for hex bit sockets when working on equipment panels, valve assemblies, manifolds, and mechanical connections that use Allen-style fasteners. The 35210-TH weighs 0.17 pounds, making it a lightweight addition to any service kit.
This hex bit socket is suited for residential and light commercial service work where 5/16-inch hex fasteners are encountered. Common applications include equipment access panel fasteners, pump and valve body bolts, and electrical enclosure hardware. It is sold individually, making it a practical replacement for a lost or worn socket in an existing set.
Designed for use with standard 1/2-inch drive ratchets, breaker bars, and extensions commonly found in trade service kits.
A licensed trade professional or experienced technician should ensure the socket is fully seated on the drive before applying torque. Always de-energize electrical equipment and relieve system pressure on pressurized assemblies before loosening or tightening fasteners. Inspect the socket for cracks or rounding before each use and replace if wear is evident.
