Screwdriver bit set YATO YT-0493 — 2 pcs, Tri-Wing and Security hex (1/4), 100 mm

YATO YT-0493 is a compact 2-piece screwdriver bit set that includes a Tri-Wing bit and a security (tamper-resistant) hex bit, both in standard 1/4" drive size. Each bit measures 100 mm in length, making them suitable for deeper recessed fasteners while remaining compatible with common 1/4" bit holders, ratchets and electric drivers. The set is intended for repair, maintenance and assembly tasks where Tri-Wing and tamper-resistant hex drives are required.

Advantages

The set provides two specialized tip types in a compact pair, reducing the need to carry multiple single bits. With 100 mm length, the bits offer improved reach to access recessed or hard-to-reach fasteners. The standardized 1/4" shank ensures compatibility with a wide range of manual and powered bit drivers. Hardened tip geometry delivers consistent engagement with Tri-Wing and security hex fasteners to minimise cam-out and wear during repeated use.

Suitable for

• Electronics repair and disassembly requiring Tri-Wing fasteners
• Maintenance of appliances and equipment with tamper-resistant hex screws
• Assembly and servicing tasks where extended-reach 100 mm bits are needed

Key specifications

• Tip types: Tri-Wing and security hex (tamper-resistant hex)
• Drive size: 1/4" (standard bit shank)
• Bit length: 100 mm each
• Set quantity: 2 pieces

How to use

Select the required bit from the set and insert its 1/4" shank into a compatible bit holder, manual driver or powered driver. Position the bit into the fastener head, apply steady axial pressure and turn the driver in the intended direction. For tamper-resistant hex screws ensure the security pin is accommodated by the bit before applying torque. Use controlled force to avoid damaging the fastener head or the bit tip.

Usage recommendations

For optimal performance, use the bits with drivers that accept 1/4" hex shanks and apply steady, aligned torque. Inspect tips before use and replace any bit that shows significant wear or deformation. When working on delicate electronics, use a torque-limited driver to prevent over-tightening.
