Paramount PAR37214 Hex Key 3/8 Inch Hex Short Arm

Product Description

The PARAMOUNT PAR37214 is a short-arm hex key with a 3/8 inch hex size, designed for driving hex socket fasteners in tight or confined spaces where a long-arm tool will not fit. The short arm configuration limits swing arc requirements, making it practical for work in crowded mechanical assemblies, panel enclosures, or equipment access areas. Overall length is 4-19/64 inches (108 mm). This type of hand tool is commonly used by HVAC technicians, plumbers, electricians, and general mechanical trades any time a hex socket cap screw or set screw needs to be turned without power tooling.

The PAR37214 is suited for general maintenance and installation tasks across residential and commercial service work. The hex end engages directly with hex socket fasteners, making it a standard carry item for service technicians working on equipment panels, motor mounts, fan assemblies, valve packing glands, and similar fastener applications. The short arm style provides higher torque input on the short end when flipped, while the long end offers better reach. Sold as a single piece per package with a minimum order quantity of 10 units.

Installation Notes

No power source shutdown is required for the hex key itself, but always de-energize and lock out equipment before accessing internal fasteners on electrical or mechanical systems per applicable safety codes. Use the short arm for high-torque driving and the long arm for faster rotation with reduced torque. Inspect the key for wear or deformation before use; a worn hex tip can round fastener sockets.
