Paramount PAR17570 Hex Key 7.00 Mm Ball End

Product Description

The PARAMOUNT PAR17570 is a metric hex key with a 7.00 mm ball end and long arm design, built for fastener access in tight or angled spaces. The ball end allows driving at angles up to 30 degrees off-axis without sacrificing consistent torque transfer. Constructed from Protanium High Torque Steel, this key handles demanding applications where standard chrome vanadium tools may flex or round out. The gray-handled long arm provides additional leverage for breaking loose stubborn fasteners. Technicians across HVAC, plumbing, and mechanical trades reach for this type of tool when servicing equipment with recessed hex fasteners.

This hex key is suited for metric fastener work in residential and commercial mechanical installations. Its long arm geometry makes it practical in panel interiors, equipment enclosures, and anywhere a standard short arm key lacks the reach or leverage. The 5.5-inch overall length keeps it compact enough for a service pouch while still delivering the arm length needed for torque on larger hex fasteners. Trade professionals use long-arm ball-end hex keys during equipment assembly, bracket adjustment, and access panel servicing.

Key Features

• 7.00 mm metric hex size fits a wide range of metric fastener heads
• Ball end allows off-axis driving up to approximately 30 degrees for working in confined spaces
• Long arm style provides increased leverage compared to standard short-arm keys
• Protanium High Torque Steel construction resists torsional stress and wear
• 5.5-inch overall length offers extended reach in equipment enclosures
• Gray handle provides visual identification and a secure grip surface

Compatibility

Designed for use with metric hex fasteners requiring a 7.00 mm drive, commonly found in HVAC equipment, mechanical assemblies, and trade hardware applications.

Installation Notes

Use on metric hex fasteners only — do not attempt to drive SAE fasteners with a metric key, as damage to both the key and fastener can result. When using the ball end for off-axis driving, apply steady controlled force to avoid tip rounding. Inspect the ball end for wear before each use; a worn tip should not be used on torque-sensitive fasteners. Store with other hex keys to prevent tip damage.
