Precision Rolled - The 29 degree ACME thread form provides both efficiency of motion and load strength. Cold formed lead screw material has a smooth finish for reduced friction and a strong grain structure for driving high loads. Maximum length of screw as is 144inch on this imperialy sized product. (Diameter 1.0inch)
 
Standard Features:

  • ACME thread sizes range between 3/16" and 5/8" in outside diameter.
  • Conforms to ANSI B1.5 and B1.8 thread standards.
  • Available in single or multiple start thread forms.
  • External threaded rods have a 2G thread fit.
  • The lead accuracy is 0.006" per foot max.
  • Standard material is 300 series Stainless Steel.
  • Surface roughness is a burnished 16 finish or better.
  • We offer many standard ACME sizes, and custom forms are available upon request.
