Critical Speed: Trapezoidal Screws

Curves are alternately broken and solid for ease of use. The line type has no significance.

NOTE: Maximum Speed is limited to 80% of the calculated Critical Speed. See pages 12-13 of our Precision Screw Assemblies Catalog for reference description on A-B-C-D end fixity.

Metric to Inch Conversion:

1 Newton = .224 lbf
1 mm = 0.039 in
1 N m = 8.85 in⋅lb
