Paramount PAR17550 Ball End Hex Key 1.50 Mm Long Arm

Product Description

The PARAMOUNT PAR17550 is a 1.50 mm metric ball end hex key designed for fastener access in tight or angled work spaces. The long arm configuration provides extended reach and added torque leverage compared to standard-length keys. Constructed from steel, this hex key is suited for repeated use in professional maintenance and installation environments. The ball end allows driving at angles up to approximately 30 degrees off-axis, making it a practical choice for field technicians working in confined equipment cabinets, junction boxes, or mechanical assemblies. Overall length is 3-1/32 inches.

This hex key is used wherever 1.50 mm metric fasteners are encountered in trade service work. Common applications include HVAC equipment panels, electrical enclosures, pump assemblies, and pool equipment components requiring small metric Allen-head fasteners. The long arm style is preferred when access depth or torque requirements exceed what a standard arm can provide. Sold individually, with a minimum order quantity of 10 units.

Installation Notes

This tool is installed and used by HVAC technicians, electricians, plumbers, and pool service professionals as part of routine equipment servicing. Always de-energize and lock out electrical equipment before accessing internal fasteners. Use the standard straight end for higher-torque applications and reserve the ball end for angled or hard-to-reach fastener positions to avoid rounding the fastener socket.
