Paramount PAR17509 Hex Key 5/32 Inch Ball End

Product Description

The PARAMOUNT PAR17509 is a 5/32-inch ball-end hex key with a long arm design, built for driving hex fasteners in tight or angled installations. Machined from steel, this L-style driver accepts the ball end on the long arm, allowing fastener engagement at angles up to approximately 25 degrees off-axis — useful when straight access is restricted. The overall length of 4-13/64 inches gives the long arm enough reach for recessed fastener seats. This tool is a standard fit for HVAC equipment panels, pump housings, and other assemblies that rely on socket-head cap screws or set screws with 5/32-inch hex drives.

This hex key is suited for service technicians working on residential and light commercial HVAC units, pool equipment, plumbing fixtures, and similar assemblies where 5/32-inch socket-head or set-screw fasteners are common. The long-arm configuration is particularly useful when torque leverage is needed on the short arm while the ball end on the long arm allows off-angle access to fasteners in confined equipment cabinets or behind panels.

Key Features

• 5/32-inch hex drive size fits standard socket-head cap screws and set screws
• Ball end on long arm allows off-axis fastener engagement in confined spaces
• Long arm style provides increased torque leverage when driving from the short arm
• Steel construction for durability under repeated service use
• Compact overall length of 4-13/64 inches suits tight equipment enclosures

Compatibility

Designed as a standard 5/32-inch ball-end hex key suitable for use with any hex socket fastener of that drive size across HVAC, plumbing, pool, and general mechanical service applications.

Installation Notes

Use the long arm for off-angle access and the short arm when higher torque is needed to seat or break loose fasteners. Power down equipment and relieve any system pressure before accessing fastener-secured panels or components. Apply steady, controlled force — ball-end engagement is not rated for high-torque impact use. Follow applicable equipment manufacturer guidelines for fastener torque requirements.
