Paramount PAR37108 Hex Key 9/64 Inch Long Arm

Product Description

The PARAMOUNT PAR37108 is a long-arm hex key sized at 9/64 inch, designed for fastening and loosening hex socket fasteners in tight or recessed locations. Made from steel, it measures 3-15/16 inches in overall length, giving technicians extra reach and leverage compared to standard-arm keys. The long arm configuration allows the short end to be used for high-torque applications and the long end for access in confined spaces. HVAC techs, plumbers, electricians, and general trade professionals keep hex keys like this in their service kits for equipment panels, access covers, and mechanical assemblies.

This hex key suits residential and light commercial service work wherever 9/64 inch hex socket fasteners are used. Common applications include tightening set screws on motors, pulleys, and fan hubs, as well as adjusting mechanical components inside HVAC units, pump assemblies, and electrical enclosures. Its compact overall length of under 4 inches makes it easy to carry in a tool pouch or bag alongside other hand tools.

Key Features

• 9/64 inch hex tip fits standard hex socket fasteners and set screws
• Long arm style provides extended reach into recessed or confined fastener locations
• Steel construction for durability under repeated torque loads
• 3-15/16 inch overall length suits tight access areas
• Inch measurement system for compatibility with standard US fasteners

Compatibility

Designed as a general-purpose hand tool compatible with any 9/64 inch hex socket fastener following inch-measurement standards, suitable for use across HVAC, plumbing, electrical, and mechanical service applications.

Installation Notes

No power source or shutoff is required for hand tool use. Select the correct hex size before applying torque to avoid rounding fastener sockets. Use the short arm end for higher torque applications and the long arm end for low-torque or access-limited situations. Inspect the tool for wear or deformation before use to prevent fastener damage.
