Lead Screws - Screws & Shafts

Lead screws, also known as power screws, are bars of lead with a thread, similar to a traditional screw but without a head. They are used in motion control to translate turning or rotating movements into a linear motion.How do they work?They sometimes work alongside nuts, a type of fastener that features a threaded hole. The threaded hole twists onto the lead screw thread. As the lead screw turns or rotates, the nut moves along the screw in a linear motion.Lead screws are available in various diameters and lengths, with a range of different pitches or lead. Types of thread:• Trapezoidal thread• Square thread• Acme thread• Sharp thread• Buttress thread• Knuckle thread• Course thread• Diamond thread
