3/4" Threaded Connection 
3/4" threaded components use standard national coarse threads. This connection type's stronger and more durable than the 5/8" threaded option, making it ideal for heavy-duty applications.
5/8" Threaded Connection 
5/8" threaded components also use standard national coarse threads. This is the most common and cost-effective connection type, and nearly all of our equipment is outfitted with it.
Signature Series Threaded Connection 
Signature Series threaded components feature a heavier thread than the 5/8" threaded option. They're robust, long-lasting, and require only 2-1/2 turns to connect or disconnect equipment. This reduces the risk of thread galling and improves efficiency. Many of our most popular tools are available with this connection type.
Hex Quick Pin Connection 
The Hex Quick Pin connection's designed for speed and efficiency, and it's our preferred connection type. Built with hardened-steel hex couplings, it offers a connection that's fast and reliable. It accepts 3/8" snapper pins or heat-treated 3/8" U-clips—snapper pins provide ease of use, while U-clips offer added durability. Torque's absorbed by the hex couplings rather than threads, which reduces wear and prevents the risk of thread galling. For bucket augers, this connection also supports reverse augering.
Quick Connect Connection 
The Quick Connect connection's designed for speed and convenience, using hardened-steel hex couplings with a button. It offers a connection that's quick and simple. Torque's absorbed by the hex couplings rather than threads, which reduces wear and prevents the risk of thread galling. For bucket augers, this connection also supports reverse augering.
Telescoping Connection 
The Telescoping connection's exclusive to our Telescoping auger systems. Built with round couplings that accept 1/4" snapper pins, it offers a connection that's quick and simple. Torque's absorbed by the round couplings rather than threads, which reduces wear and prevents the risk of thread galling. This connection also supports reverse augering.
