Screwdriver bit YATO YT-04354 — 12-spline flange M12, length 100 mm, 1 pc, 1/2" shank

YATO YT-04354 is a single 12-spline flange screwdriver bit M12 with a 100 mm working length and a 1/2" shank. It is manufactured from chromium-vanadium steel and designed for use with drivers and adaptors that accept a 1/2" connection. The geometry of the 12-spline flange head provides precise engagement with compatible M12 12-spline fasteners, making it suitable for professional automotive and industrial repair tasks where controlled torque transfer and repeatable fit are required.

Advantages

The bit’s 12-spline flange profile ensures stable contact with matching fasteners, reducing the risk of rounding and improving torque transfer. Its 100 mm working length gives improved access to recessed or hard-to-reach fasteners while the 1/2" shank ensures compatibility with common impact driver adaptors and sockets. Made of chromium-vanadium steel, the bit offers balanced strength and wear resistance appropriate for repeated use in workshop conditions.

Suitable for

• Removal and installation of M12 12-spline flange fasteners
• Automotive repair and maintenance tasks
• Industrial equipment assembly and servicing
• Use with impact drivers and hand tools that accept a 1/2" shank

Key specifications

• Tip type: 12-spline flange (M12)
• Working length: 100 mm
• Shank: 1/2" (25.4 mm) compatible
• Material: Chromium-vanadium steel
• Quantity: 1 piece

How to use

Select an appropriate 1/2" adaptor or chuck on the impact driver or hand tool and securely seat the YATO YT-04354 bit. Align the 12-spline flange tip with the matching M12 fastener, apply steady axial pressure, and operate the driver at a controlled speed to avoid cam-out. For removal, start at low speed to ensure proper engagement before increasing torque; for installation, monitor torque or use a torque-limiting tool when required to prevent over-tightening.

Usage recommendations

Inspect the bit and fastener for damage before use. Use impact-rated tools and appropriate safety equipment. Replace the bit if the tip shows significant wear or deformation. For precision torque applications, use a calibrated torque tool rather than relying solely on an impact driver.
