Metric Precision Acme 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.
360 brass nuts have excellent machinability. 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
Combine these setup studs with T-slot nuts, flanged nuts, setup clamps, or setup blocks to clamp and hold workpieces, vises, and other objects onto your fixturing table. Also known as double-ended studs, they have threads on both ends. One end threads into a T-slot nut or flanged nut inside the table. The other end passes through a setup clamp and secures with a nut and washer. The middle of the stud is unthreaded for gripping and adjusting the stud.
These setup studs are also used to align parts during assembly. One end of the stud is threaded into the part being added, and the other end fits into the mounting hole of the mating part. Because the studs don't have a head, you have the option to thread them into holes from either end, but they require a nut. You can adjust the distance between the mating parts by tightening and loosening the nut.
Steel studs are low- or medium-strength carbon steel. With no protective coating, they have poor corrosion resistance. Avoid using them in humid and damp environments.
Black-oxide steel studs have a protective coating that resists corrosion in dry environments.
Some of these studs meet DIN dimensional and material standards so designers and engineers know that they're compatible with other parts and tools.
