Lead Screw - Square, Acme, And Buttress Thread Forms | High Efficiency, Precision Motion Translation, Ideal For Machine Tools And Jacks

A leadscrew (or lead screw), also known as a power screw or translation screw, is a screw designed to translate radial motion into linear motion. Common applications are machine slides (such as in machine tools), vises, presses, and jacks.
Types of lead screw we manufacture-
Square thread form
Square threads are named after their square geometry. They are the most efficient power screw, but also the most difficult to machine, thus the most expensive.
Acme thread form
Acme threads have a 29 thread angle, which is easier to machine than square threads. They are not as efficient as square threads, due to the increased friction induced by the thread angle
Buttress Thread Form-
Buttress threads are of a triangular shape. It combines the advantages of the square and acme thread forms with only one disadvantage, it only works in one direction
