Screwdriver bit YATO YT-04319 — Torx T70, length 55 mm, shank 1/2" (25.4 / 2 mm)

YATO YT-04319 is a single Torx T70 screwdriver bit designed for heavy-duty fastening tasks. With a working tip size of T70 and a total length of 55 mm, this bit fits applications that require a robust Torx interface. The bit has a 1/2" (25.4 / 2 mm) shank compatible with standard 1/2-inch holders and impact sockets, making it suitable for use with impact drivers, torque wrenches with adapters, and hand-operated holders that accept a 1/2" shank.

Advantages

The YATO YT-04319 Torx T70 bit is manufactured from chromium-vanadium steel for improved strength and wear resistance under high-torque conditions. Its 55 mm length provides a balance between access to recessed fasteners and control during tightening or loosening operations. The 1/2" shank ensures solid engagement with standard sockets and holders, reducing the risk of slipping or rounding the Torx profile during heavy use.

Suitable for

• Automotive repair and maintenance where large Torx fasteners are used
• Industrial assembly and disassembly involving high-torque Torx screws
• Construction and heavy equipment applications requiring durable bits
• Use with impact drivers, torque tools, and socket adapters accepting 1/2" shanks

How to use

Insert the 1/2" shank of the YT-04319 bit into a compatible 1/2" holder, socket, or impact adapter until it is securely seated. Align the Torx T70 tip with the corresponding fastener head and apply steady torque while maintaining axial alignment to avoid cam-out. For powered tools, start at low speed to ensure correct seating, then increase speed or torque as required by the task. Inspect the bit tip before use for signs of wear or damage.

Usage recommendations

Use the bit with tools and sockets rated for the intended torque. Keep the Torx tip clean and free of debris to preserve engagement accuracy. Replace the bit if the tip becomes rounded or damaged to avoid fastener damage.
