Paramount PAR37274 Hex Key 9 Mm Short Arm 4 in

Product Description

The PARAMOUNT PAR37274 is a short-arm hex key designed for fastening and loosening hex socket fasteners in metric applications. Built from Protanium High Torque Steel, it delivers the torsional strength needed for high-load driving without rounding out fastener sockets. The 9 mm hex tip engages fasteners with a full hex-end contact pattern. Overall length is 4 inches, putting this key in the compact range suited for confined spaces where a long arm would bind or obstruct access. At 0.19 pounds, it is light enough for tool-belt carry on any service call.

This hex key is used across mechanical, plumbing, HVAC, and equipment service work wherever metric hex socket fasteners are encountered. The short-arm design is well suited to panel removal, bracket installation, valve body service, and equipment access covers in residential and light commercial settings. The gray handle provides a visual reference in mixed-metric toolkits. Sold individually, with a minimum order quantity of 5 units.

Installation Notes

This tool is used by HVAC technicians, plumbers, electricians, and general service trades for fastener removal and installation. Confirm the fastener drive size before applying torque to avoid socket damage. Inspect the hex tip for wear before use on critical fasteners. Store separately from SAE hex keys to prevent mix-ups on metric fastener applications.
