Signature series components feature a heavier thread than 5/8in 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.


  • Heavier thread design.
  • Connection and disassembly with 2 1/2 turns.
  • Fast connection speed without risk of galling.
