Screwdriver YATO YT-79970, C45 steel blade, 900 g, 365 mm nylon handle

YATO YT-79970 is a heavy-duty screwdriver designed for mechanical and construction tasks that require high torque and long-term durability. It features a C45 steel blade for strength and wear resistance and a 365 mm nylon handle engineered to provide a firm grip while resisting abrasion. Weighing 900 g, this model is built to withstand demanding use in professional and DIY environments.

Advantages

The C45 steel blade delivers improved toughness and resistance to bending under load compared with softer steels, extending the working life of the tool. The long 365 mm nylon handle increases leverage, enabling higher torque with controlled hand placement. At 900 g, the tool offers a solid, stable feel that aids in precision when applying force. Materials and construction are chosen to reduce wear and support repeated use in mechanical and construction settings.

Suitable for

• Mechanical assembly and disassembly tasks
• Construction and site maintenance work
• Heavy-duty household repairs and DIY projects
• Applications requiring extended reach and greater torque

Key specifications

• Blade material: C45 steel
• Handle material: nylon
• Handle length: 365 mm
• Weight: 900 g
• Tool type: heavy-duty screwdriver

How to use

Select the appropriate tip or mating fastener and position the screwdriver blade fully into the fastener recess to ensure contact across the driving surfaces. Hold the 365 mm nylon handle with a firm grip and apply controlled force, using the handle length to increase leverage when higher torque is required. Maintain alignment between the blade and fastener to avoid slipping and potential damage to the fastener head or blade. After use, clean the blade and store the tool in a dry place to minimise corrosion and wear.

Usage recommendations

Use the screwdriver for tasks within its mechanical limits; avoid applying excessive impact or using it as a pry bar. Regularly inspect the blade for deformation or wear and replace the tool if the driving surfaces are damaged. For fasteners requiring very high torque, use appropriate torque-limiting tools or power equipment.
