Acme thread form

Acme threads are a common screw thread profile, which offers high strength with ease of machining and assembly. Typically found where large loads or accuracy is required as in vises or the lead screw of a lathe. Standardized variations include multiple-start threads, left-hand threads, and self-centering threads which are less likely to bind under lateral forces.
