Hex Drive Threaded Rods
Threaded Tip
Unthreaded Tip
A hex drive on one end allows these rods to be turned with a hex key for ease of installation. Use them to connect parts with coarse threads to parts with fine threads. They're high-strength black-oxide steel and corrosion resistant in dry environments.
Rods with an unthreaded tip thread into nuts more easily, reducing the chance of damaging threads.
