- Inertia Welded to the shaft ends to allow attachment of extensions for deeper penetration into ground when needed.
- On both the box end and pin end of every extension we use 4140 & 4125 hardened alloy that we inertia weld to the tube body. We then quench and temper the connection, normalize and then heat treat to get back to full strength.
- The industry standard has always been to simply drill holes in the ends of a lesser grade tube, considerably limiting it’s torque capacity.
- All connections are precision machined allowing the loads to be shouldered from tube to tube, while the industry standard is to rely on the bolt connection for it’s strength.
