Product information

Description

The Wera 780 B adaptor converts a 3/8" square drive into a 1/4" hexagon drive (DIN ISO 1173-C 6.3), allowing use of 1/4" hex bits with 3/8" square-drive tools. With a compact body measuring approximately 30 mm in length and a diameter around 3 cm, it is built for precise torque transfer and secure bit retention.

Advantages

This adaptor provides compatibility between 3/8" square-drive tools and 1/4" hex bits without modifying either tool. Its robust Wera construction ensures durability under repeated use while maintaining accurate torque transfer. The compact dimensions make it easy to handle and store in a toolbox.

Suitable for

  • Using 1/4" hex bits with 3/8" square-drive ratchets or handles
  • Professional mechanical and assembly work requiring fast bit changes
  • DIY tasks where different drive sizes must be adapted quickly
