Screwdriver bit YATO YT-04397 — Hex (metric) 14 mm, length 100 mm, 1 pc, 1/2" shank

YATO YT-04397 is a single hex (metric) screwdriver bit with a 14 mm tip diameter and a total length of 100 mm. The bit features a 1/2" (12.7 mm) shank designed to fit standard 1/2" bit holders, torque tools and impact drivers that accept this shank size. Intended for metric 14 mm hex fasteners, this rigid bit offers compatibility with a range of hand and power tool setups used in assembly, maintenance and repair operations.

Advantages

The 14 mm hex tip provides secure engagement with metric hex fasteners, reducing the risk of rounding. A 100 mm length gives additional reach for recessed or hard-to-access fasteners while keeping leverage and control. The 1/2" shank ensures compatibility with widely used drivers and sockets, enabling quick bit changes and use with higher-torque tools. The single-piece design minimizes play between driver and fastener for consistent torque transfer during assembly and service tasks.

Suitable for

• Assembly of machinery and equipment with metric 14 mm hex fasteners
• Maintenance and repair work in automotive and industrial settings
• Installation tasks requiring extended reach to recessed bolts
• Use with torque wrenches and impact drivers accepting a 1/2" shank

Key specifications

• Tip type: Hex (metric)
• Tip diameter: 14 mm
• Overall length: 100 mm
• Shank type and size: 1/2" (standard 12.7 mm) round/hex shank for bit holders
• Quantity in pack: 1 piece

How to use

Insert the 1/2" shank fully into a compatible bit holder, socket adapter or directly into an impact driver chuck designed for 1/2" bits. Ensure the bit is seated firmly to prevent slipping. Select appropriate torque settings on powered tools when tightening or loosening fasteners; for manual torque tools, apply steady pressure and maintain alignment with the fastener to avoid cam‑out. After use, inspect the tip for wear and replace the bit if the hex edges become rounded.

Usage recommendations

For best results, use the bit with tools rated for the required torque and with impact‑rated holders for powered impact applications. Keep the bit clean and store it in a protective holder to prolong service life. Avoid using a worn or damaged bit on critical fasteners to maintain reliable engagement and prevent fastener damage.
