Screwdriver Bit Set Wera 05136393001

The Wera 05136393001 screwdriver bit set contains 11 high-quality 25 mm bits designed for a 1/4" hexagonal shank. The set groups common tip types — metric Hex, Phillips, Pozidriv and Torx Plus — to cover a wide range of fastening tasks. Compact and organized for easy storage, the bits deliver consistent fit and repeatable torque transfer for workshop, maintenance and assembly work.

Advantages

Bits of uniform 25 mm length provide predictable engagement depth and improved access in confined spaces. Hardened and finished to resist wear, the tips maintain precise geometry for reduced cam-out and reliable screw engagement. Compatibility with standard 1/4" hex holders and bit drivers makes the set versatile for hand tools, bit holders, and compact powered drivers. The mix of Hex, Phillips, Pozidriv and Torx Plus tips covers both common and specialist fasteners to reduce the need for separate tools.

Suitable for

• General maintenance and repair work
• Furniture assembly and installation
• Electronics and appliance servicing requiring compact bit length
• Workshop and professional fitting tasks

Key specifications

• Number of bits: 11
• Bit length: 25 mm

How to use

Select the correct tip for the screw head and insert the 1/4" hex shank into a compatible driver, bit holder or quick-change chuck. Apply axial pressure while rotating at a controlled speed; for powered drivers, set torque and speed appropriate to the fastener material to avoid damage. Inspect the tip engagement before each use to ensure proper seating and minimize cam-out. After use, clean debris from the bit and store bits in their holder to protect the tips and maintain organization.

Usage recommendations

Use the appropriate tip profile for the screw to maximize service life and maintain fastener integrity. Avoid excessive lateral force and disengage power before changing bits. For high-torque applications, use longer or purpose-designed bits and drivers to reduce stress on 25 mm bits.
