Paramount PAR17510 Hex Key 3/16 Inch Ball End

Product Description

The PARAMOUNT PAR17510 is a 3/16-inch ball-end hex key designed for professional fastener work in tight or angled access points. The long-arm configuration provides increased torque leverage on hex fasteners, while the ball end allows engagement at off-axis angles without removing the key. Constructed from steel, this tool handles the repetitive demands of trade service environments. At 4.5 inches overall length, it fits standard tool pouches and roll organizers. Licensed tradespeople and service technicians keep this size on hand for a wide range of HVAC, plumbing, pool equipment, and mechanical fastener applications.

This hex key is suited for residential and light commercial service work where 3/16-inch hex fasteners are encountered. Common applications include set screw adjustment on motor shafts, access panel hardware, pump assemblies, and valve packing glands. The ball-end geometry is particularly useful when full axial alignment with the fastener is restricted by adjacent components or enclosure walls. It is sold individually per package, with a minimum order quantity of 10 units, making it appropriate for shop restocking or fleet tooling programs.

Key Features

• 3/16-inch hex drive fits standard set screws and socket-head cap screws
• Ball-end tip allows off-axis engagement for use in restricted spaces
• Long-arm style delivers greater torque leverage compared to short-arm versions
• 4.5-inch overall length fits standard tool rolls and pouches
• Steel construction for durability under repeated service use
• Inch measurement system; no metric conversion required for standard trade fasteners

Compatibility

Designed as a general-purpose 3/16-inch ball-end hex key suitable for any application requiring an L-style hex driver of that size in trade and mechanical service work.

Installation Notes

Use the long arm for initial fastener engagement and high-torque driving, and switch to the short arm for fast spinning in low-torque stages. The ball end should not be used as the primary drive end when maximum torque is required, as off-axis loading can accelerate tip wear. No power tools or special certifications are required; standard hand tool practices apply.
