Screwdriver bit holder YATO YT-04394 Chromium-Vanadium Steel Cr-V 1/2" (25.4 mm) hex shank, 100×8 mm

YATO YT-04394 is a screwdriver bit holder made from Chromium-Vanadium Steel (Cr-V) with a 1/2" (25.4 mm) hex shank and a working length of 100 mm. The holder has an 8 mm outer diameter and a 2 mm internal shank diameter designed to accept and secure interchangeable bits for use with hand sockets, ratchets and compatible power tools. Built for tasks that require strong magnetic or mechanical retention, this bit holder provides stable bit seating and reliable torque transfer between driver and fastener.

Advantages

The Cr-V construction offers enhanced durability and resistance to wear compared with standard carbon steel, enabling longer service life under repeated torque loads. The 1/2" hex shank provides wide compatibility with common sockets and drive adapters, while the 100 mm length gives extra reach in recessed or hard-to-access fasteners. The holder's precise machining ensures a snug fit with standard screwdriver bits and reduced play during operation.

Suitable for

• Automotive repair and maintenance where deep or recessed fasteners are present
• Mechanical assembly and disassembly tasks requiring high torque transfer
• Workshop and industrial use with ratchets, torque wrenches and impact drivers (where compatible)
• Home DIY projects that need reliable bit retention and extended reach

Key specifications

• Material: Chromium-Vanadium Steel (Cr-V)
• Shank type: 1/2" (25.4 mm) hex shank
• Overall length: 100 mm
• Outer diameter: 8 mm
• Inner shank diameter (bit interface): 2 mm
• Compatibility: interchangeable screwdriver bits and standard 1/2" drive tools

How to use

Insert a compatible bit into the holder until it seats firmly; verify that the bit is secured and does not wobble. Fit the 1/2" hex shank into a matching socket, ratchet or adapter and apply torque gradually, ensuring the bit remains properly engaged. For repeated bit changes, pull the bit straight out of the holder and replace as needed. When used with power tools, confirm tool compatibility and follow the power tool manufacturer's speed and torque recommendations.

Usage recommendations

Use the holder within the mechanical limits of its material and the bits installed. Avoid excessive side-loading or prying motions that can cause bit or holder deformation. Inspect for wear or damage before each use and replace the holder if visible cracking, rounded corners, or excessive play occurs.
