Metric Precision Lead Screws and Nuts
Pair with a motor in automated motion and positioning applications. A tight thread fit allows these lead screws and nuts to make accurate, repeatable starts and stops. Also known as single-start and self-locking lead screws and nuts, they have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won’t unexpectedly move when the lead screw is at rest. To ensure compatibility, select components that have the same thread size.
Lead screws are 1018 carbon steel for good machinability.
932 bearing bronze nuts have good machinability and wear resistance. Manganese bronze nuts have good strength and wear resistance.
Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

Setup Studs
Secure setup clamps and fixtures to your machine table, or assemble heavy machines, such as engine mounts. These studs act as a pilot when connecting parts since they’re headless, which eases installation. Unlike a bolt, which has a head, they let you access parts from either end, but they require nuts to hold the part. Pair them with a T-slot or flanged nut when securing to a machine table. Or, put a nut on before your part to work as a float, allowing you to adjust the height of your part. The unthreaded middle is useful for gripping and adjusting. Also known as double-ended studs.
Steel studs are stronger than stainless steel studs. But, unfinished steel studs will rust from air and moisture. Black-oxide steel studs resist rusting in dry environments.
DIN studs meet dimensional and material requirements.
