Paramount PAR37202 Hex Key 0.05 Inch Short Arm

Product Description

The PARAMOUNT PAR37202 is a short-arm hex key with a 0.05 inch hex drive size, designed for fastening and loosening hex socket cap screws, set screws, and similar fasteners in tight or recessed spaces. The short arm configuration provides increased torque in confined areas where a long-arm key would not clear surrounding components. At 1-39/64 inches overall length and weighing just 0.001 pounds, this is a compact, lightweight hand tool suited for bench work, field service, and assembly tasks across HVAC, plumbing, electrical, and general mechanical trades.

This hex key is intended for applications requiring a 0.05 inch drive in locations with limited swing clearance. Typical uses include adjusting set screws on motor shafts, linkage collars, valve stems, and other small mechanical assemblies. The short arm design is common in precision equipment service where standard-length keys create clearance conflicts. It is sold individually with a minimum order quantity of 10 units, making it practical for stocking in service vans or shop tool kits.

Installation Notes

Always de-energize or shut off the equipment being serviced before adjusting any fasteners. Ensure the hex key is fully seated in the fastener socket before applying torque to prevent rounding of the drive recess. Inspect the key for wear or deformation before each use and replace if the hex faces show signs of rounding or cracking.
