Truss head screws Use a reduced profile and a broad head that provides a bigger bearing surface area. They are ideal for applications where a significant degree of clamping pressure is required.
The design choice involving ball screws and lead screws is sophisticated. Ball screws cost additional up front, but they have an inclination to deliver improved accuracy and lessen servicing costs In the long term. However, the positional precision and elevated load dealing with of ball screws might be overkill for a few purposes; in this sort of conditions, a lead screw could be high-quality.
Trapezoidal threads are also ready to deal with superior axial masses. These threads, because of their production relieve and load dealing with, are very popular.
