Wiha 32688 Professional PlusMinus SL/PZ1 Screwdriver Bit, 90 mm, 2 Pieces

The Wiha 32688 Professional PlusMinus SL/PZ1 screwdriver bit is a high-quality tool engineered for precision and reliability in electrical installations. Measuring 90 mm in length, this bit features a specialized combination profile designed to securely fit PlusMinus screws, which are commonly found in terminal blocks, fuse boxes, and circuit breakers. This professional-grade accessory is built to withstand the rigors of daily industrial use while providing a stable connection that minimizes the risk of slippage or damage to screw heads.

Advantages

The primary benefit of this screwdriver bit is its ability to significantly increase work efficiency during electrical assembly tasks. The extra-long 90 mm reach provides optimal access to low-lying or recessed screws that are difficult to reach with standard-length bits. Its durable construction ensures a long service life, maintaining consistent performance even under heavy-duty conditions. By providing a perfect fit for PlusMinus profiles, it reduces the effort required for fastening and helps prevent accidental damage to sensitive electrical components.

Suitable for

• Electrical installation and maintenance
• Working with terminal blocks and fuse boxes
• Industrial assembly lines
• Professional manual fastening tasks

This bit may not be suitable for standard Phillips or Pozidriv screws that do not feature the specific PlusMinus profile, as using it on incompatible fasteners may lead to cam-out or damage to the tool and the screw. It is also not intended for high-torque impact driving applications where specialized impact-rated bits are required.

Key specifications

• Profile: PlusMinus SL/PZ1
• Length: 90 mm
• Drive: 1/4 inch hexagonal
• Material: High-quality chrome-vanadium steel
• Quantity: 2 pieces

To use the Wiha 32688 bit, insert the 1/4-inch hexagonal end into a compatible manual screwdriver handle or a power tool bit holder. Ensure the bit is fully seated before applying torque. Align the tip carefully with the PlusMinus screw head to ensure a secure engagement. Apply steady, even pressure while turning to maintain the integrity of the screw and the bit profile.

What to consider before purchase

• Verify that your fasteners are specifically PlusMinus SL/PZ1 type
• Ensure your tool holder is compatible with 1/4-inch hex bits
• Check if the 90 mm length is appropriate for your specific workspace depth

For optimal performance and longevity, always ensure the bit is clean and free of debris before use. Avoid using the bit as a pry bar or for tasks outside of its intended fastening application to prevent premature wear.
