Paramount PAR17572 Hex Key 8mm Ball End Long Arm

Product Description

The PARAMOUNT PAR17572 is a metric ball-end hex key designed for fastener driving in confined or angled workspaces. Built from steel with a long arm configuration, it delivers the leverage needed for high-torque applications while the ball-end tip allows off-axis engagement up to approximately 25 degrees. The 8 mm hex size suits medium-to-large fasteners common in mechanical assemblies, equipment enclosures, and HVAC component mounting. At 6 inches overall length, it fits into tight clearances without sacrificing handle grip. This tool is used by HVAC technicians, plumbers, electricians, and general mechanical trades for routine service and installation work.

This hex key is suited for metric fastener applications in residential and commercial mechanical systems. Common uses include tightening set screws on fan hubs, motor mounts, pump couplings, and equipment access panels. The long arm style increases torque output compared to standard-arm keys, making it a practical choice when working on stubborn or over-tightened metric fasteners in the field or shop. Sold individually.

Key Features

• Ball-end tip allows off-axis fastener engagement in tight or obstructed spaces
• Long arm design provides increased torque leverage over standard-arm hex keys
• 8 mm metric hex size for medium-to-large metric fastener applications
• 6 inches overall length for reach into deep or recessed fastener locations
• Steel construction for durability under repeated use

Compatibility

Designed for use with 8 mm internal hex (socket head) metric fasteners found in mechanical, HVAC, plumbing, and electrical equipment assemblies.

Installation Notes

Use the ball end for initial engagement at an angle, then switch to the straight end for final torque to avoid rounding the fastener socket. Always confirm the hex size matches the fastener before applying torque. Inspect the key for wear or deformation before each use and replace if the tip shows rounding or cracking.
