Screwdriver Bit Set Yato YT-0414

The Yato YT-0414 screwdriver bit set contains five 12-spline flange and 9.5 mm slot screwdriver bits with a 25.4 / 2 mm (1/2") shank size. This combination provides compatibility with a wide range of ratchets, impact drivers and adaptors commonly used in workshops and on-site. The bits are designed for repeated fastening and unfastening tasks where a robust connection between the fastener and the tool is required, delivering consistent engagement with splined flange fasteners and slotted screws.

Advantages

The set offers a compact selection of frequently used bit types in a single package, manufactured to meet the mechanical demands of both professional and home users. The 12-spline profile improves torque transfer and reduces cam-out during tightening, while the 9.5 mm slot blades provide a straightforward solution for slotted fasteners. The 1/2" shank size ensures stable fitting in standard sockets and drive tools, supporting secure operation under moderate to high torque loads.

Suitable for

• Automotive repair and maintenance tasks involving spline flange fasteners
• General mechanical assembly and disassembly work
• Workshop and garage use with impact drivers and ratchet handles
• Domestic DIY projects requiring slotted screwdriver bits

Key specifications

• Number of pieces: 5
• Tip types: 12-spline flange and 9.5 mm slotted
• Shank size: 25.4 / 2 mm (1/2")
• Compatibility: fits standard 1/2" drives and common adaptors
• Intended use: fastening and loosening spline flange and slotted screws

How to use

Select the appropriate bit from the set that matches the fastener type and insert it firmly into a compatible 1/2" drive socket, impact driver adaptor or ratchet. Ensure the bit is fully seated before applying torque. For removal, apply steady, controlled force to avoid slipping; for installation, maintain alignment between the bit and fastener to achieve correct engagement and reduce wear. After use, store bits in their case or a designated holder to protect tips from damage and to keep the set organized.

Usage recommendations

Use the 12-spline flange bits for fasteners that require higher torque transfer and the 9.5 mm slotted bit for simple slotted screws. Avoid excessive side-load on the bits and use appropriate torque settings on power tools. Inspect bit tips regularly and replace any worn or deformed bits to maintain safe and effective operation.
