Paramount PAR37148 Hex Key 0.90 Mm Long Arm

Product Description

The PARAMOUNT PAR37148 is a metric hex key designed for fastener work in tight or hard-to-reach spaces. It features a long arm design with a hex end, allowing greater reach and improved leverage compared to standard-length keys. The hex size is 0.90 mm, sized for small metric fasteners commonly found in HVAC equipment panels, electrical enclosures, and plumbing fixtures. Constructed from Protanium High Torque Steel, this key is built to resist rounding and deformation under load. Overall length is 2.7 inches, with a handle color of gray for quick visual identification in a tool pouch or kit.

This hex key is suited for service technicians who work on equipment requiring small metric fasteners. Typical applications include tightening or removing set screws, access panel hardware, and equipment mounting fasteners in residential and light commercial settings. The long arm style provides torque advantage when driving fasteners in confined areas, making it practical for field service and bench work alike. It is sold as an individual unit with a minimum order quantity of 10 pieces.

Installation Notes

Use this hex key by hand only; do not use with power drivers or cheater bars, as the long arm geometry is not rated for impact torque. Ensure the key is fully seated in the fastener socket before applying torque to avoid rounding the drive recess. When servicing energized equipment, power down all circuits and follow applicable NEC or IFGC lockout-tagout procedures before accessing fasteners inside enclosures or control cabinets.
