3/4'' threaded connections are made of powder-coated chromoly or chromoly steel.
5/8'' threaded and quick connect extensions are either chromoly or stainless steel.

AMS signature series, threaded, and quick connect connections are used to connect AMS cross handles or slide hammers to AMS extensions,auger heads, and samplers. Each connection type has advantages that will make it more appropriate for particular uses or users. Please take into consideration that not all items will be available in every connection type. Contact us if you are unsure which connection type to use.
AMS recommends using non-adhesive fluoropolymer tape and wrench-tightening AMS threaded and signature series connections to help prevent the components from being damaged during heavy use and to minimize wear and tear over time. This also helps prevent threaded components from being difficult to disconnect after use with a slide hammer, hammer-head cross handle, or after hard twisting with a standard cross handle or ratcheting handle.
Signature series components feature a heavier thread than 5/8'' threaded connections. They are generally more robust and last longer under heavy use. Signature components can be connected and disconnected with only 2 1/2 turns, and have less risk of galling. Our most popular slide hammers, augers, core samplers, and soil sampling kits are available with signature series connections.
AMS 5/8'' and 3/4'' threaded connections use standard, national course, threads. 3/4'' are used with the new AMS professional line of augers and samplers. 5/8'' connections are the most
common and least expensive. Augers, core samplers, probes, slide hammers, hammer-head handles, and kits are available with threaded connections.
The AMS quick connect button-and-hex coupling system allows components to connect and disconnect faster and with less hassle than threaded or signature series systems. When in use,
the torque exerted on the system is placed on the hex – rather than threads – which makes the quick connect connection durable and prevents the components from binding together. Quick connect connections also allow for reverse augering with either a rubber-coated cross handle or ratcheting cross handle. Most augers and some soil sampling kits are available with AMS quick
connect connections, but the connections are not compatible with AMS slide hammers or the hammer-head cross handle.
