The PARAMOUNT PAR37110 is a 3/16 inch long-arm hex key designed for fastener-driving applications where additional torque and reach are required. The long arm configuration provides mechanical advantage over standard-length hex keys, making it suitable for deep or recessed fasteners. Constructed from steel, this hex key delivers the durability needed for repetitive use in field and shop environments. The hex end engages hex socket fasteners directly and is sized for common 3/16 inch applications. Overall length is 4.5 inches. This tool is used by HVAC technicians, plumbers, electricians, and other trade professionals during equipment assembly, service, and installation tasks.
This hex key is appropriate for general trade use wherever 3/16 inch hex socket fasteners are encountered. Common applications include tightening set screws on motor shafts, fan hubs, valve handles, electrical enclosure hardware, and similar components found in HVAC, plumbing, and electrical systems. The long arm style suits situations where a standard short-arm key lacks sufficient reach or torque leverage. Sold individually with a minimum order quantity of 10 units, making it practical for stocking service vans or tool kits.
Designed for use with 3/16 inch hex socket fasteners in standard inch-measurement applications across HVAC, plumbing, electrical, and general mechanical service work.
This tool is used by trade professionals during equipment service and installation. Ensure the hex key is fully seated in the fastener socket before applying torque to avoid rounding the drive recess. No power tools or calibrated torque equipment are typically required for hand hex key use. Follow equipment manufacturer service procedures when tightening or loosening fasteners on live systems.
