Screwdriver bit set YATO YT-0417 — 14 pcs, Torx T20–T55, 1/2" (25.4 mm) shank

YATO YT-0417 is a 14-piece screwdriver bit set designed for working with Torx fasteners. The set contains a selection of Torx sizes from T20 to T55 and features a 1/2" (25.4 mm) shank that fits impact drivers, ratchets and common bit holders. It is intended for assembly, maintenance and repair tasks where Torx profiles and higher torque transmission are required.

Advantages

The bits are made to provide reliable engagement with Torx heads and to transfer higher torque thanks to the 1/2" shank. Compatibility with impact drivers and hand ratchets increases versatility across workshop and field applications. The set covers a broad range of commonly used Torx sizes, reducing the need to switch between different tool holders during jobs that require larger fasteners.

Suitable for

• Automotive assembly and repair
• Industrial maintenance and equipment servicing
• Construction and mechanical installation work
• Home workshop and DIY projects involving Torx fasteners

Key specifications

• Bit type: Torx (T20, T25, T30, T40, T45, T50, T55)
• Number of pieces: 14
• Shank diameter and length: 1/2" (25.4 mm) shank
• Intended drive compatibility: impact drivers, ratchets and bit holders
• Application torque range: suited for higher torque transmission compared to smaller shanks

How to use

Select the Torx bit that matches the fastener head size and securely insert the 1/2" shank into the tool holder or chuck. For hand-ratchet use, ensure the bit is seated fully in the holder to prevent slipping. When using an impact driver, apply controlled bursts rather than continuous high power to avoid damage to the fastener or bit. After use, store bits in their case or organizer to protect tips and maintain fit accuracy.

Usage recommendations

Use the correct Torx size to minimize cam-out and wear. For heavily corroded or damaged fasteners, inspect the fastener and bit before applying high torque; consider lubrication or extraction methods if required. Maintain bits by keeping them clean and dry and replace worn bits to preserve drive engagement and safety.
