Paramount PAR17580 Ball End Hex Key 12 Mm Long Arm

Product Description

The PARAMOUNT PAR17580 is a long-arm ball end hex key designed for fastening and loosening hex socket fasteners in confined or angled work spaces. Manufactured from Protanium High Torque Steel, it delivers increased torsional strength over standard chrome vanadium hex keys, reducing the risk of rounding or snapping under load. The ball end allows up to approximately 30 degrees of angular engagement, letting technicians drive fasteners without a straight-line approach. At 8-45/64 inches overall length, the long arm provides extended reach and added torque leverage on the drive end. This tool is used by HVAC technicians, plumbers, electricians, and general tradespeople working on equipment with metric hex fasteners.

The PAR17580 is suited for metric fastener applications across residential and commercial trade work. Common use cases include tightening set screws on motor couplings, adjusting blower wheel hubs, servicing pump assemblies, and accessing recessed fasteners on electrical enclosures or equipment panels. The 12 mm hex size covers larger fasteners found on heavy mechanical assemblies typical in commercial HVAC, pump, and piping systems. The gray handle provides visual identification in tool storage.

Key Features

• Ball end tip allows angular engagement for fasteners in tight or obstructed locations
• Protanium High Torque Steel construction for increased strength under high-torque applications
• Long arm design provides extended reach and greater torque leverage
• 12 mm metric hex size for larger hex socket fasteners
• 8-45/64 inches overall length for deep access and controlled driving
• Gray handle for easy identification in tool kits

Compatibility

Designed for use with 12 mm metric hex socket fasteners commonly found in commercial and residential mechanical, HVAC, plumbing, and electrical equipment assemblies.

Installation Notes

Use the ball end for angled engagement only when torque demands are moderate — apply full torque through the straight end to avoid tip deformation. Power down and de-energize equipment before accessing fasteners on electrical or HVAC assemblies. Inspect the hex key tip before use and replace if worn or rounded to prevent fastener damage. No special certifications are required to use hand tools, but always follow applicable safety procedures for the equipment being serviced.
