Ruuvauskärjet Bosch Extra Hard 3 kpl PZ 1 25 mm

Bosch Extra Hard 3 pcs PZ 1 25 mm screwdriver bits provide a compact, durable solution for Pozidriv fastening tasks. Each bit in this set measures 25 mm in length and features a PZ 1 tip designed to fit Pozidriv screws precisely. The 1/4" hex shank ensures compatibility with most manual and powered bit holders, offering a reliable interface for transfer of torque and controlled fastening in varied applications.

Advantages

The Extra Hard material treatment increases wear resistance and extends service life under repeated use. Precision-machined tips ensure accurate seating in Pozidriv screw heads, reducing cam-out and minimizing damage to both screw and bit. The standardized 1/4" hex shank allows quick bit changes and broad compatibility with common drivers, impact drivers, and bit holders. Compact 25 mm length is suitable for confined spaces while maintaining effective torque transmission.

Suitable for

• Assembly and disassembly of Pozidriv screws in furniture and cabinetry
• Electrical and electronic enclosures requiring small Pozidriv fasteners
• General maintenance and DIY projects with medium torque requirements

Key specifications

• Tip type: Pozidriv (PZ 1)
• Quantity: 3 pieces
• Length: 25 mm
• Shank: 1/4" hex
• Material treatment: Extra hard surface for increased wear resistance

How to use

Select a PZ 1 bit from the set and insert the 1/4" hex shank into the driver chuck or bit holder until it locks. Position the tip into the Pozidriv screw head, apply moderate axial pressure, and operate the driver at a controlled speed appropriate for the screw material. For powered drivers, use steady speed and avoid excessive force to prevent stripping. After use, store bits in a dry place to maintain the extra hard surface condition.

Recommendations

For best results, match the PZ 1 tip size exactly to the screw head to reduce wear. Use these Extra Hard bits for tasks with frequent bit changes or higher abrasion; avoid applying extreme bending loads that exceed the bit's design limits. Inspect tips regularly and replace if visibly worn or rounded.
