YATO YT-5538 is a 40-piece screwdriver bit set designed for use with bit holders and powered screwdrivers. The set includes a broad selection of bits, including Torx tips, hex (H) and metric (M) sockets in two lengths, and sizes suitable for workshop, automotive and home maintenance tasks where Torx and hex fasteners are common. Bits are manufactured from AISI S2 tool steel to provide wear resistance and consistent fit with compatible drivers.
Advantages
The set combines a comprehensive range of sizes in compact, organised packaging to keep bits accessible and secure. Use of AISI S2 steel and precision machining ensures dimensional accuracy, good torque transfer and improved durability compared with generic bits. Two length options for many sizes increase versatility for recessed or shallow fasteners, and the inclusion of common Torx sizes meets typical automotive and electronics service requirements.
Suitable for
- Automotive repair and maintenance where Torx and metric fasteners are used
- General assembly and disassembly of machinery and equipment
- Home repairs, furniture assembly and DIY projects
- Workshop and service environments requiring a compact set of interchangeable bits

How to use
Select the bit that matches the fastener head and insert it into a compatible bit holder or powered screwdriver. Ensure the bit seats fully in the fastener to avoid cam-out and damage. For recessed or hard-to-reach screws, use the longer (75 mm) bits; for standard or shallow screws, use the 30 mm bits. When using power tools, apply steady, moderate speed and controlled torque to avoid stripping heads. After use, return bits to their labelled positions in the case to maintain organisation and reduce wear.
Usage recommendations
Inspect bits regularly for signs of wear or deformation and replace damaged bits to maintain safe operation and consistent fastening. Use bits designed for the specific fastener type and size, and match the bit length to the access conditions to ensure correct torque delivery and reduce the risk of fastener or bit damage.
