Paramount PAR17556 Hex Key 3.00mm Ball End Long Arm

Product Description

The PARAMOUNT PAR17556 is a metric ball-end hex key designed for fastener access in tight or angled locations. The 3.00 mm hex tip fits M3-class socket head cap screws and similar metric fasteners common in HVAC equipment panels, pump assemblies, and electrical enclosures. The ball end allows up to 30 degrees of off-axis engagement, reducing the need to reposition in confined spaces. The long arm style provides increased torque leverage compared to a standard short-arm key. Overall length is 3.875 inches. The shaft and body are steel construction for durability under repeated use by service technicians across HVAC, plumbing, and electrical trades.

This hex key suits residential and light commercial service work where metric fasteners are encountered on equipment covers, motor mounts, valve assemblies, and control panels. The long arm configuration makes it practical for reaching recessed fasteners without full perpendicular access. At 3.875 inches overall length, it fits comfortably in a technician tool pouch or service kit. The 3.00 mm metric size is a common dimension on imported equipment and components increasingly found in modern HVAC and mechanical systems.

Key Features

• 3.00 mm metric hex drive fits M3-class socket head fasteners
• Ball-end tip allows off-axis engagement in restricted spaces
• Long arm style increases torque reach over short-arm versions
• 3.875 inches overall length fits standard tool pouches
• Steel construction for durability in trade service applications

Compatibility

Designed as a general-purpose metric hex key suitable for 3.00 mm socket head fasteners found across HVAC equipment, pump assemblies, electrical enclosures, and mechanical components requiring metric tooling.

Installation Notes

No power-down or system shutoff is required for hand tool use, but always de-energize electrical equipment before removing access panels or enclosure covers. Confirm the hex key seats fully in the fastener socket before applying torque to avoid rounding the drive recess. Ball-end engagement is best suited for light to moderate torque; use the straight end for final tightening where possible.
