Paramount PAR50409 Preset Torque Screwdriver

Product Description

The PARAMOUNT PAR50409 is a preset torque screwdriver designed for applications where consistent, repeatable torque delivery is critical. Set to a fixed torque value of 155.2 in/oz (1.100 Nm), this single-piece tool removes guesswork from fastener installation. The straight handle and 0.1968-inch drive size make it suitable for confined or precision-access work. Technicians in HVAC, electrical, and general mechanical service use preset torque screwdrivers to avoid over-tightening fasteners on control boards, terminal blocks, and panel components. The tool ships as a single unit and weighs 0.21 pounds, making it easy to carry in a service kit.

This preset torque screwdriver is used across light industrial and field-service environments where specific fastener torque requirements must be met without a full torque wrench setup. It is well suited for low-torque fastener work on electrical enclosures, equipment panels, and small mechanical assemblies. The compact straight handle fits standard service pouches and is appropriate for both bench work and on-site installation tasks performed by licensed technicians and experienced service professionals.

Installation Notes

This tool is used by HVAC technicians, electricians, and mechanical service professionals for torque-sensitive fastener work. Always de-energize equipment and follow lockout/tagout procedures before accessing electrical panels or control boards. Do not use this screwdriver as a standard driver or apply force beyond the preset torque rating, as doing so may damage the tool or the fastener. Follow applicable NEC or equipment-specific guidelines when working on electrical enclosures.
