Apex EX-374-B 3/8 in Drive Socket Extension 1.375 in

Product Description

The APEX EX-374-B is a 3/8 inch drive socket extension designed for use with standard 3/8 inch drive ratchets and torque wrenches. At 1.375 inches overall length, this compact extension provides the reach needed in tight-clearance fastener applications without adding unnecessary length to the drive train. Constructed from steel and manufactured to ANSI and DIN standards, it is built for the repetitive demands of professional trade work. Mechanics, HVAC technicians, and plumbers rely on short extensions like this one when working in confined equipment compartments where a longer extension would foul against surrounding components.

This extension is suited for light to medium-duty fastener work across residential and commercial service applications. Its short overall length makes it particularly useful in equipment panels, junction boxes, and mechanical assemblies where clearance is limited. It pairs with 3/8 inch drive sockets for standard hex fastener removal and installation in service and maintenance scenarios.
