Paramount PAR37117 Hex Key 9/16 Inch Long Arm

Product Description

The PARAMOUNT PAR37117 is a long-arm hex key designed for fastening and loosening hex socket fasteners in professional trade applications. It features a 9/16-inch hex end and measures 9 inches in overall length, providing extended reach and increased torque leverage compared to standard-arm designs. The key is manufactured from Protanium High Torque Steel, a material engineered for high-stress drive applications where standard alloy steel may flex or round out. Licensed HVAC technicians, plumbers, electricians, and mechanical contractors use long-arm hex keys when access depth or torque demand exceeds what a short-arm tool can deliver.

This hex key is suited for residential and commercial maintenance, installation, and repair tasks where 9/16-inch hex fasteners are used. The long arm provides a mechanical advantage that makes it well-suited for stuck or high-torque fasteners encountered during equipment installation or field service. The gray handle color aids quick identification in a tool pouch or kit. It ships as a single unit and is appropriate for any trade professional who regularly works with inch-measurement hex fasteners.

Installation Notes

Use by any trade professional working with hex socket fasteners. Ensure the hex key is fully seated in the fastener socket before applying torque to avoid rounding the drive. De-energize or shut off equipment before accessing fasteners on powered systems. Inspect the tool for cracks or deformation before each use and replace if damage is observed.
