Paramount PAR37211 Hex Key 7/32 Inch Short Arm

Product Description

The PARAMOUNT PAR37211 is a short-arm hex key with a 7/32 inch hex drive, designed for fastening and loosening hex socket screws in confined or tight-clearance spaces. The short arm measures 3 inches overall length, making it well-suited for applications where a standard long-arm key would contact surrounding hardware or enclosures. It features a straight hex end for direct socket engagement. HVAC technicians, plumbers, electricians, and general trade professionals keep short-arm hex keys on hand for equipment access panels, setscrew collars, valve packings, and motor mounts where swing clearance is limited.

This hex key is appropriate for residential and light commercial trade work. Typical uses include tightening setscrews on fan blades, shaft collars, and coupling assemblies during HVAC equipment service, as well as general mechanical fastening tasks across plumbing, electrical, and pool equipment maintenance. The 7/32 inch drive size is a common specification for setscrews found on small-to-mid-range blower wheels and motor shaft assemblies. Sold individually per package.

Installation Notes

This tool is installed by hand with no power source required. De-energize and lock out any equipment before accessing internal fasteners per applicable safety codes. Ensure the hex key is fully seated in the fastener socket before applying torque to avoid rounding the drive. Inspect the tool for wear or deformation before each use and replace if the flats show signs of damage.
