1" SQ Bit Holders

Atlas Copco 1" square drive bit holders adapt large-drive nutrunners and impact tools to accept screwdriving bits, enabling a single high-torque tool to serve both nutrunning and bit-driving applications without changing the tool itself. Precision-machined to ensure a secure bit-to-holder interface, they maintain full torque transmission at the elevated torque levels associated with 1" SQ tooling.

• Adapts 1" SQ nutrunners to accept screwdriving bits
• Enables one high-torque tool to cover multiple application types
• Precision-machined for secure bit retention at high torque levels
• Custom configurations available for non-standard requirements
