SGT – Standard Ground Threads are ground from high carbon alloy steel that has been induction heat treated to a depth greater than the thread. Standard stocked screws have a lead accuracy tolerance of ±0.0005 in/ft and are supplied with internally preloaded nuts which must be factory assembled. Ground screws are used for applications that require smooth operation, precise positioning, and repeatability.
For convenience, SGT screws can be supplied completely machined and assembled with nuts and EZZE-MOUNTS ready for assembly. Should a standard assembly not fit the application, Nook can machine the screw to your specific design requirements. Ball nut configurations can be engineered to application requirements.
