Screwdriver bit set YATO YT-0491 — 2 pcs, Torx T15 & T27, 100 mm, 1/4" shank

YATO YT-0491 is a 2-piece screwdriver bit set containing Torx T15 and T27 bits. Each bit measures 100 mm in length and has a 1/4" (6.35 mm) hex shank compatible with standard bit holders and cordless/drill drivers. The set is intended for fastening Torx fasteners in automotive, electronics and general maintenance applications, providing extended reach and compatibility for both professional and DIY tasks.

Advantages

The bits are made of steel for reliable strength and wear resistance. The 100 mm length gives extra reach in recessed or hard-to-access fasteners, while the 1/4" hex shank ensures secure fitment in common bit holders and quick-change chucks. Including two commonly used Torx sizes (T15 and T27) covers a range of fastening needs without needing full-size sets.

Suitable for

• Automotive repair and maintenance
• Electronics assembly and repair
• Furniture assembly and household repairs
• General fastening tasks with Torx fasteners

Key specifications

• Number of pieces: 2
• Tip type: Torx (T15, T27)
• Length: 100 mm each
• Shank: 1/4" (6.35 mm) hex
• Material: Steel

How to use

Select the correct Torx size (T15 or T27) for the fastener, insert the 1/4" hex shank into a compatible bit holder, driver or cordless drill, then engage the bit with the fastener and apply steady torque. Use the longer 100 mm length to reach recessed screws; ensure bit is fully seated to avoid cam‑out or damage to the fastener head.

Usage recommendations

For longer tool life and consistent performance, avoid excessive side load, keep bits clean and inspect for wear; replace bits that show rounding or deformation. Match the torque setting of power drivers to the fastener and material to prevent over‑tightening.
