Paramount PAR17514 Hex Key 3/8 Inch Ball End

Product Description

The PARAMOUNT PAR17514 is a long-arm ball-end hex key sized at 3/8 inch, designed for driving hex fasteners in tight or off-angle locations. The ball-end tip allows up to 30 degrees of angular engagement without repositioning the tool, which speeds up fastener work in confined spaces. At 6.75 inches overall length, the long arm provides extended reach and increased torque leverage compared to standard-length hex keys. The tool is machined from steel for durability under repeated use. It is suited for mechanical assembly, equipment service, and maintenance tasks across HVAC, plumbing, electrical, and general trade work.

This hex key is used wherever 3/8 inch hex-drive fasteners are encountered — including set screws, cap screws, and socket-head bolts found in blower assemblies, pump housings, valve actuators, electrical enclosures, and mechanical equipment panels. The long arm style is preferred when access is restricted or when additional torque is needed on stubborn fasteners. Suited for both shop and field use by HVAC technicians, plumbers, electricians, and general mechanical service professionals.

Compatibility

Designed for use with 3/8 inch hex-drive fasteners in standard inch-measurement applications across mechanical, HVAC, plumbing, and electrical service work.

Installation Notes

No power source or lockout/tagout procedure is required for this hand tool. Always ensure equipment is de-energized, depressurized, or otherwise safely isolated before driving or removing fasteners on any mechanical or electrical assembly. Use the long arm for initial loosening or final tightening; use the short arm when higher torque is needed to avoid overloading the tool. Inspect the tool for wear or deformation before each use.
