Paramount PAR17502 Ball End Long Arm Hex Key

Product Description

The PARAMOUNT PAR17502 is a ball end, long arm hex key designed for fastener drive applications in tight or angled workspaces. Measuring 2-27/32 inches in overall length, the ball end tip allows for off-axis engagement at angles where a standard hex key cannot reach straight on. Constructed from steel, this hand tool delivers the durability expected in trade and mechanical service environments. It is sized within the less-than-4-inch overall length range, making it a compact but capable driver for hex fasteners encountered in HVAC equipment, plumbing fixtures, electrical enclosures, and general mechanical assemblies.

This hex key is suited for service technicians and installers who regularly encounter recessed or hard-to-reach hex socket fasteners during equipment installation or field repairs. The long arm style provides additional torque leverage compared to short arm variants, and the ball end enables engagement at off-center angles without fully aligning the tool to the fastener axis. It is appropriate for residential and light commercial service work across HVAC, plumbing, and electrical trades.

Key Features

• Ball end tip allows off-axis fastener engagement for work in confined spaces
• Long arm design increases torque leverage over short arm hex keys
• Steel construction provides durability for repeated field use
• Compact 2-27/32 inch overall length fits in standard tool pouches and bags
• Inch measurement system for compatibility with standard SAE fasteners

Compatibility

Designed as a general-purpose hand tool suitable for hex socket fasteners in HVAC, plumbing, electrical, and mechanical service applications where a ball end long arm hex key is specified.

Installation Notes

This tool is used by technicians across HVAC, plumbing, and electrical trades for loosening or tightening hex socket fasteners during equipment service. Always de-energize electrical equipment and shut off fluid or gas supply before performing any mechanical service that requires fastener removal. Do not use a hex key as a pry tool or apply extension force beyond normal hand torque. Inspect the tool for wear or deformation before each use.
