WERA – TORX PLUS® Security 25 IPR Bit 1/4″ for Bosch Gen 4 retaining plates

The WERA TORX PLUS® Security 25 IPR bit is manufactured from through-hardened chrome-vanadium steel and specifically designed for the security screws used on Bosch 4th generation motor retaining plates.

The improved TORX PLUS® profile provides a larger contact surface compared to standard TORX, ensuring better force transmission, increased durability and a precise fit.
For these screws, using the correct security bit is mandatory to prevent rounding or damaging the screw head.
