Paramount PAR37247 Hex Key 0.70 Mm Short Arm

Product Description

The PARAMOUNT PAR37247 is a metric short-arm hex key designed for driving hex fasteners in confined spaces where a standard-length arm will not fit. It is manufactured from Protanium High Torque Steel, a material engineered to resist rounding and deliver higher torque capacity than conventional alloy steel hex keys. The key measures 1-13/64 inches overall length and is sized at 0.70 mm across the hex. The short arm configuration reduces swing arc requirements, making it practical in tight assemblies. Technicians working on HVAC equipment, pump assemblies, plumbing fixtures, and mechanical controls will find this key sized for small metric fasteners common in those applications.

This hex key is suited for residential and light commercial service work where 0.70 mm metric hex fasteners appear. Typical install scenarios include adjusting set screws on valve stems, motor mounts, and small equipment panels. The short arm style is especially practical when access depth is limited by surrounding components or enclosure walls. It is sold individually with a minimum order quantity of 10 units, making it appropriate for stocking in a service van kit or tool crib.

Key Features

• Protanium High Torque Steel construction resists rounding and fastener cam-out under load
• 0.70 mm metric hex size targets small set screws and fasteners common in mechanical equipment
• Short arm style reduces required clearance for insertion and turning
• 1-13/64 inch overall length suits restricted-access service environments
• Gray handle coloring for quick visual identification in a multi-key set

Compatibility

Designed as a standard short-arm metric hex key for use with any 0.70 mm hex-socket fastener in HVAC, plumbing, pool, and general mechanical service applications.

Installation Notes

Power down or isolate any equipment before accessing fasteners on energized assemblies. Use the short arm for initial engagement and final torque in tight spaces; switch to the long arm end if additional torque leverage is required and clearance allows. Inspect the hex tip for wear before use — a worn tip can damage small fasteners that are difficult to replace in the field. No special certifications are required to use hand tools, but follow applicable trade and safety codes for the system being serviced.
