Wiha 28591 Phillips PH 0 Screwdriver Bit 175 mm

The Wiha 28591 Phillips PH 0 screwdriver bit is a precision-engineered tool designed for demanding fastening tasks where accuracy and reliability are paramount. With a total length of 175 mm, this bit features an extra slim blade geometry, making it an ideal choice for reaching screws in confined or narrow spaces that standard bits cannot access. Constructed from high-quality chrome-vanadium-molybdenum steel, the bit is through-hardened and chrome-plated to ensure exceptional durability and resistance to wear during professional use.

Advantages

This screwdriver bit significantly enhances operational efficiency by providing a perfect fit for Phillips PH 0 screws, minimizing the risk of cam-out and damage to the fastener head. The specialized Wiha ChromTop finish on the tip ensures that the bit maintains a secure grip and precise fit over extended periods of use. Its robust construction from high-grade steel alloys guarantees longevity, while the integrated color-coding system allows for quick and easy identification of the bit size in a busy workshop environment.

Suitable for

• Precision assembly tasks in electronics
• Maintenance work in confined spaces
• Controlled fastening applications requiring specific torque
• Professional mechanical and electrical repairs

When it may not be suitable

This bit is specifically designed for PH 0 Phillips screws and will not be compatible with other screw head types such as Torx, Pozidriv, or slotted fasteners. Due to its slim profile and small tip size, it is not intended for high-torque applications involving large screws or heavy-duty construction tasks where significant force could lead to tip deformation.

Key specifications

• Drive type: Phillips PH 0
• Length: 175 mm
• Material: Chrome-vanadium-molybdenum steel
• Finish: Chrome-plated with ChromTop tip
• Standards: DIN ISO 8764-1
• Color-coding: Dark blue

How to use

To use the Wiha 28591 bit, insert it into a compatible screwdriver handle or power tool that accepts 4 mm bits. Ensure the bit is fully seated within the screw head before applying pressure. Align the tool perpendicularly to the screw to maintain optimal contact. When used with a torque-controlled tool, ensure the device is calibrated to the recommended torque settings to prevent over-tightening or damage to the fastener.

What to consider before purchase

• Verify that your current screwdriver handle or tool holder is compatible with 4 mm bits.
• Ensure the PH 0 size matches the specific screw head requirements of your project.
• Check the depth of the access area to confirm that the 175 mm length is sufficient for your needs.

Usage recommendations

For optimal performance and to maintain the integrity of the ChromTop tip, always ensure the bit is clean and free of debris before use. Avoid using the bit as a prying tool, as this can compromise the precision-engineered tip geometry.
