Paramount PAR17508 9/64 Inch Ball End Hex Key

Product Description

The PARAMOUNT PAR17508 is a 9/64 inch ball-end hex key with a long arm design, built for fastener access in tight or angled spaces. The ball end allows up to 30 degrees of off-axis engagement, making it practical in confined assembly and service environments. The long arm provides extended reach and greater torque leverage compared to standard-length keys. Constructed from steel, this hex key is suited for repeated use in mechanical and trade service applications. It measures 3-15/16 inches overall length and weighs 0.23 pounds per unit.

This hex key is used in mechanical, HVAC, pool equipment, and plumbing fixture service work where socket head cap screws or set screws require a 9/64 inch hex drive. The long arm configuration is particularly useful when fasteners are recessed or when additional torque is needed during installation or removal. It is sold individually and is well-suited for technicians who need a single replacement or supplemental key for their existing set.

Installation Notes

This tool is installed by hand and requires no special certifications or codes for use. Ensure the correct hex size is matched to the fastener before applying torque to avoid rounding. When using the ball end for angled engagement, apply steady, controlled force to prevent tip wear or fastener damage. Keep the tool clean and inspect for wear or deformation before each use.
