Connection Design: The square drive extension rod has 12.5 mm square drive interfaces at both ends, creating a secure fit for compatible wrench and socket connections.

Anti-Drop Feature: The connector head uses a steel ball anti-drop design to help keep the socket in place during use, reducing the chance of slipping at the joint.

Practical Use: This wrench extension rod is shaped for stable access in compact work areas, with a clamp-groove diameter marked 21 mm for clear fit reference.
