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, please select components that have the same thread direction, thread size, and number of thread starts.

Lead Screws—Right-Hand Thread


	Right-Hand Threads

1018 Low-Carbon Steel—Carbon steel lead screws and flanges have good machinability.

Black-Oxide 4140 Alloy Steel—Black-oxide alloy steel lead screws are hard and strong. They have mild corrosion resistance and a dark surface color.

304 Stainless Steel—304 stainless steel lead screws have good corrosion resistance.

Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

Lead Screws—Left-Hand Thread


	Left-Hand Threads

1018 Low-Carbon Steel—Carbon steel lead screws and flanges have good machinability.

Black-Oxide 4140 Alloy Steel—Black-oxide alloy steel lead screws are hard and strong. They have mild corrosion resistance and a dark surface color.

304 Stainless Steel—304 stainless steel lead screws have good corrosion resistance.

Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

Lead Screws—Right-Hand and Left-Hand Thread


	Right-Hand-and-Left-Hand Threads

Right-hand-and-left-hand threaded lead screws have right-hand threads on one end and left-hand threads on the other. Use them where you want to drive nuts in opposite directions at the same time, such as for widening and narrowing chutes on packing and assembly lines. Note: A short length of threading at the center of the lead screw is not usable.

Black-Oxide 4140 Alloy Steel—Black-oxide alloy steel lead screws are hard and strong. They have mild corrosion resistance and a dark surface color.

Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

Fast-Travel Precision Acme Lead Screws and Nuts

Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start. The threads have a tight thread fit for accurate, repeatable starts and stops. Pair with a motor in automated motion and positioning applications. To ensure compatibility, please select components that have the same thread direction, thread size, and number of thread starts.

Lead Screws—Right-Hand Thread

1018 Low-Carbon Steel—Carbon steel lead screws and flanges have good machinability.

Black-Oxide 4140 Alloy Steel—Black-oxide alloy steel lead screws are hard and strong. They have mild corrosion resistance.

Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.
