Paramount PAR35589 9 Piece Fold-up Hex Key Set

Product Description

The PARAMOUNT PAR35589 is a 9-piece fold-up hex key set designed for fastener work across a range of inch-size hex fasteners. Built from steel, the set covers a hex size range of 5/64 inch to 1/4 inch and folds into a compact plastic holder measuring 4.5 inches in length. The folding handle design allows the tech to apply torque directly or flip a key out and use it as a driver, keeping all nine sizes organized and accessible on the job. At 0.38 pounds, this set is light enough to carry in a tool pouch on service calls.

This hex key set suits residential and commercial service work where inch-size hex fasteners are common. HVAC technicians, plumbers, electricians, and pool service pros encounter hex-head set screws and cap screws on equipment panels, motor mounts, valve stems, and junction fittings. The fold-up format makes it a practical addition to a field service bag or van stock where saving space without sacrificing coverage matters.

Installation Notes

No special certifications are required to use hand tools, but always follow applicable safety codes for the trade discipline involved.
