The TEKTON SHB12200 is a 3/8 inch drive hex bit socket designed for driving 1/8 inch hex fasteners. It measures 1.9 inches overall length and is suited for use with any standard 3/8 inch drive ratchet, extension, or torque wrench. This socket gives mechanics, HVAC technicians, and general tradespeople a reliable tool for accessing hex-head screws and bolts in tight quarters. The compact form factor makes it practical for equipment panels, access covers, and mechanical assemblies where clearance is limited.
This hex bit socket is a common choice for service work across HVAC equipment, plumbing fixtures, electrical enclosures, and light mechanical applications. It fits standard 3/8 inch drive tool sets, making it easy to integrate into an existing socket collection. The 1/8 inch hex size is frequently encountered on set screws, grub screws, and small fasteners found in motor mounts, valve assemblies, and equipment covers in both residential and light commercial settings.
Designed as a standard 3/8 inch drive hex bit socket compatible with 3/8 inch drive ratchets, breaker bars, extensions, and torque wrenches from any manufacturer following standard drive sizing.
Always power down or de-energize equipment before accessing fasteners on electrical or HVAC panels. Ensure the socket is fully seated on the drive tool and hex fastener before applying torque to prevent rounding. This tool is intended for use by qualified tradespeople following applicable local codes and manufacturer service procedures.
