Paramount PAR17576 Ball End Hex Key 10 Mm Long Arm

Product Description

The PARAMOUNT PAR17576 is a long-arm ball end hex key designed for metric fastener applications in maintenance, mechanical assembly, and trade service work. Built from steel, it delivers the durability needed for repeated use in demanding environments. The 10 mm hex size suits larger fasteners common in HVAC equipment panels, pump assemblies, and mechanical systems. The ball end allows engagement at angles up to approximately 30 degrees off-axis, useful when working in confined or obstructed spaces. At 6-45/64 inches overall length, the long arm provides extended reach and increased torque leverage compared to standard-length keys. Machinists, millwrights, HVAC technicians, and plumbers reach for this tool when standard short-arm keys cannot access recessed or deeply set fasteners.

This hex key is suited for residential and commercial maintenance environments where metric fasteners are common. Typical applications include tightening or loosening set screws, cap screws, and socket head fasteners on equipment such as motors, fan assemblies, valve actuators, and pump housings. The long arm configuration is especially practical in panel interiors and tight equipment cabinets where a full wrench swing is not possible. This tool is sold individually with a minimum order quantity of 5 units.

Installation Notes

This tool is used by mechanical and trade professionals for fastener installation and removal. Confirm the fastener is the correct 10 mm hex size before applying torque to avoid rounding the socket. When using the ball end, keep engagement angle as low as practical to reduce wear on both the key and the fastener. Store hex keys in a dry location to prevent surface corrosion.
