Paramount PAR37120 Long Arm Hex Key 7/8 Inch

Product Description

The PARAMOUNT PAR37120 is a long arm hex key designed for high-torque fastening applications where standard-length tools lack reach or leverage. Built from Protanium High Torque Steel, this 7/8 inch hex key delivers the strength required for heavy-duty fastener engagement. The overall length measures 12.7031 inches, giving technicians the extended arm needed to access recessed fasteners or apply greater torque with less effort. This tool is suited for HVAC equipment assembly, mechanical contractors, and industrial maintenance professionals who work with large hex socket fasteners on a regular basis.

The PAR37120 is appropriate for commercial and industrial service environments where 7/8 inch hex drive fasteners are used. The long arm configuration allows access to fasteners in tight or recessed locations while the Protanium High Torque Steel construction resists twisting and deformation under load. The gray handle and hex end design are compatible with standard manual hex key applications across a range of trade service scenarios.
