Bosch 43 Piece Nut Driver and Screwdriver Bit Set

The Bosch 43 Piece Nut Driver and Screwdriver Bit Set is a comprehensive mixed bit set designed for universal screw-driving across a wide range of professional and trade applications.

Manufactured from S2 Modified Steel with an optimised heat treatment process, each bit delivers extra-hard durability and consistent performance across all materials. The tapered torsion zone is a key engineering feature, absorbing torque peaks and vibrations during driving to reduce the risk of cam-out and bit wear — particularly valuable when working at speed with a drill driver.

The 1/4-inch external hex shank ensures a strong, secure connection in both three-jaw chucks and 1/4" internal hex tool holders. Bits are colour-coded by type for fast identification on site, and the set is housed in a robust storage box that keeps everything organised and protected during transport.

With 43 pieces covering Phillips, Pozi, slotted, hex, Torx, Tamper-proof Torx, and magnetic nut setters, this set is well suited to electricians, joiners, carpenters, and general contractors who need a reliable, versatile bit set for everyday use.
