Paramount PAR50405 Preset Torque Screwdriver 0.1968 in Drive

Product Description

The PARAMOUNT PAR50405 is a preset torque screwdriver designed for applications requiring controlled, repeatable fastening force. It operates within a torque range of 84.7 to 85.0 inch-ounces (0.600 Nm), making it well suited for precision assembly work where over-tightening can damage components or under-tightening can cause failures. The straight handle design provides consistent grip and control during use. With a drive size of 0.1968 inches, this single-piece tool is built for technicians who need reliable torque output without manual adjustment. It weighs 0.21 pounds and fits easily into a service kit or tool pouch.

This preset torque screwdriver is used in light-duty precision fastening scenarios across HVAC, electrical, and general trade applications. It is particularly useful when assembling or servicing small components where fastener torque must stay within a defined range to avoid stripping threads or cracking housings. The preset design eliminates the need to set torque before each use, reducing error during repetitive tasks on the job site or in a shop environment.

Installation Notes

This tool is installed by hand and requires no power source. Before use, confirm the drive bit is fully seated and secure. Do not attempt to adjust or override the preset torque mechanism, as doing so can void calibration and produce inaccurate output. Store in a protective case or pouch to prevent damage to the preset clutch mechanism.
