Crescent CHBS5N Hand Hex Bit Socket 3/8 in Drive

Product Description

The CRESCENT CHBS5N is a hand hex bit socket designed for driving hex fasteners in tight-tolerance assembly and service work. Built with a 3/8 inch drive and a 5/16 inch hex bit, it fits standard 3/8 inch drive ratchets, extensions, and breaker bars. The overall length is 1.9 inches with a bit length of 1.35 inches, keeping the profile compact for access in confined spaces. Finished in chrome over a steel body, this socket is suited for HVAC equipment assembly, electrical enclosure hardware, plumbing fixture work, and general mechanical service where hex-head fasteners are common. It meets ASME B107.5 standards for hand socket dimensions and performance.

This hex bit socket is appropriate for residential and light commercial service applications. HVAC technicians commonly use 5/16 inch hex drive sockets when servicing equipment panels, blower assemblies, and access covers secured with hex-head cap screws. Electricians and plumbers encounter similar fasteners on junction boxes, valve actuators, and equipment mounting hardware. The 3/8 inch drive size is the standard mid-range drive used by most field technicians for day-to-day service calls.

Installation Notes

This socket is intended for use by qualified trade professionals including HVAC technicians, electricians, and plumbers. Always verify the fastener hex size before applying torque to avoid rounding the fastener head. Inspect the socket for cracks or wear before each use and replace if the drive or bit shows deformation. Do not use hand-rated sockets with high-torque pneumatic or hydraulic impact tools unless the socket is rated for impact use.
