Round Leadscrew Custom Made Yellow Zinc Plating

Round leadscrew is a round-headed leadscrew. A leadscrew (or lead screw), also known as a power screw or translation screw, is a screw used as a linkage in a machine, to translate turning motion into linear motion. Because of the large area of sliding contact between their male and female members, screw threads have larger frictional energy losses compared to other linkages. They are not typically used to carry high power, but more for intermittent use in low power actuator and positioner mechanisms. Common applications are linear actuators, machine slides (such as in machine tools), vises, presses, and jacks. Ever Hardware provides custom-made fasteners and customizable packaging.
Leadscrews are manufactured in the same way as other thread forms (they may be rolled, cut, or ground).
A lead screw is sometimes used with a split nut also called half nut which allows the nut to be disengaged from the threads and moved axially, independently of the screw’s rotation, when needed (such as in single-point threading on a manual lathe).
The advantages of a round leadscrew are:
Large load carrying capability
Compact
Simple to design
Easy to manufacture; no specialized machinery is required
Large mechanical advantage
Precise and accurate linear motion
Smooth, quiet, and low maintenance
Minimal number of parts
Most are self-locking
The disadvantages are that most are not very efficient. Due to the low efficiency, they cannot be used in continuous power transmission applications. They also have a high degree of friction on the threads, which can wear the threads out quickly. For square threads, the nut must be replaced; for trapezoidal threads, a split nut may be used to compensate for the wear.
