Description
The Square Adapter 114×70 mm is designed for installing screw piles with a square shaft. It connects the hydraulic drive head to the helical pile head, providing a tight and centered fit that allows smooth torque transfer without misalignment or play — essential for heavy-duty work and consistent performance.
Made of durable carbon steel and precisely machined, the adapter maintains its geometry and reliability even after hundreds of installation cycles. The 114×70 mm size fits the most common square-section screw piles used in various foundation systems. Other dimensions and configurations can be produced upon request to match specific project needs.
The adapter is compatible with both Iron-Mechanics screw pile drivers: Handheld (Falcon) and Self-propelled (Cougar). A simple yet robust component that ensures stable torque transmission and makes screw pile installation easier, safer, and more predictable on any job site.
