Paramount PAR17574 Ball End Hex Key 9 Mm Long Arm

Product Description

The PARAMOUNT PAR17574 is a metric ball end hex key designed for fastener drive applications where straight-line access is not always possible. The ball end tip allows engagement with hex fasteners at angles, which speeds up work in confined spaces. Built from Protanium High Torque Steel, this key is engineered to handle demanding torque loads without deforming the drive tip. The long arm style provides added leverage on stubborn fasteners. Overall length is 6-13/64 inches, and the hex size is 9 mm. This tool is used by HVAC technicians, plumbers, electricians, and general mechanical trades as part of a standard hand tool kit.

The PAR17574 is suited for residential and commercial service work where metric hex fasteners are encountered on equipment panels, motor mounts, valve assemblies, and similar hardware. The long arm format makes it practical in installations where reaching into equipment enclosures is required. The gray handle provides grip reference in a multi-key set. This key ships as a single unit and is intended for professional trade use where tool quality directly affects fastener and equipment integrity.

Key Features

• Ball end tip allows fastener engagement at off-axis angles
• Long arm style increases leverage for high-torque applications
• Protanium High Torque Steel construction resists tip deformation under load
• 9 mm metric hex size for compatibility with metric fastener stock
• 6-13/64 inches overall length provides reach into confined spaces
• Gray handle for visual identification in multi-key sets

Compatibility

Designed as a general-purpose metric hex key for use with 9 mm hex socket fasteners found across HVAC, plumbing, electrical, and mechanical trade applications.

Installation Notes

No power lockout is required for hand tool use, but always de-energize and lock out equipment before servicing fasteners on electrical panels, motor assemblies, or pressurized systems. Use the straight end for initial fastener seating and full torque, and reserve the ball end for intermediate turns at angle. Avoid applying full-force torque through the ball end, as ball end geometry reduces maximum torque capacity compared to the straight end.
