1. Tops of Nuts. Tops of nuts shall be flat and chamfered, the length of chamfer at hex corners shall be from 5 to 15 percent of the basic thread size. The surface may be slightly convex or rounded.

2. Bearing Surface. Bearing surface shall be at right angle to axis of the threaded hole within a tolerance of 2 degrees; therefore, the maximum total angularity of bearing surface would equal the tangent of specified angle times the diameter of the flange.

3. Concentricity of Tapped Hole. Axis of tapped hole shall be concentric with axis of nut body within a tolerance equal to 3 percent (6 percent FIM) of the maximum width across flats.

4. Countersink. Tapped hole shall be countersunk on the bearing face and may be countersunk on the top. The maximum countersunk diameter shall be the thread basic (nominal) major diameter plus 0.030 in. for 3/8 in. nominal size nuts and smaller, and 1.08 times the basic major diameter for nuts larger than 3/8 in. No part the thread portion shall project beyond the bearing-surface.

Application of IFI 145 Hex Flange Nuts:
