3/4" Drive Dial Torque Wrench w/ Light Signal 70-350 ft-lbs(96-4 - Precision Instruments

The Precision Instruments D4F350CFNL is a professional-grade 3/4" drive dial torque wrench engineered for demanding automotive and industrial applications. Delivering exceptional accuracy from 70-350 ft-lbs (96-480 N·m), this tool provides precise torque measurement for critical fasteners, ensuring reliable assembly and maintenance procedures. Its robust construction and unique torsion bar design make it an indispensable tool for mechanics and technicians.

Key Features

• Exceptional Accuracy: Achieves accuracy within 2% of the reading from 20% of full scale to full scale, both clockwise and counterclockwise, making it highly reliable for precise torque requirements.
• Torsion Bar Design: Features a patented design with a direct connection from the square drive to the dial, eliminating the influence of hand-hold position on accuracy, unlike traditional bending beam wrenches.
• Dual Scale Readout: Clearly displays primary capacity from 70-350 lb·ft in 5 lb·ft increments and secondary capacity from 96-480 N·m in 10 N·m increments for versatile use.
• Compact and Tapered Nose: Designed for enhanced maneuverability and access in confined working spaces, improving operational efficiency.
• Light Signal Option: Includes a light signal for clear indication of achieved torque, especially useful in noisy environments or when the dial is not directly in line of sight.
• Professional Grade Compliance: Meets or exceeds applicable requirements of ANSI / ASME B107.14M, GGG-W-00686C, BS6073:1988, and ISO6789, ensuring quality and reliability.

Applications

This 3/4" drive dial torque wrench is ideal for a wide range of tasks requiring accurate torque application on larger fasteners. It is commonly used in heavy-duty automotive repair, such as truck and bus chassis work, suspension components, and engine assembly. In industrial settings, it is suitable for machinery maintenance, structural steel assembly, and pipeline flange connections where precise torque is critical for operational safety and integrity.
