3 TERMINOLOGY
For definitions of other terms relating to fasteners or component features thereof used in this Standard, refer to ASME B18.12.
4 DIMENSIONS
Unless otherwise specified, all dimensions in this Standard arc inches and shall be as specified in Table 1 and sections 6 through 9. All dimensions apply before plating or coating is specified. When plating or coating is specified, the finished product dimensions shall be agreed upon between the supplier and purchaser.
5 NUT DESIGNS AND PROPERTY GRADES
This Standard covers top insert, two-piece construction nuts that derive their prevailing-torque characteristics from an insert, usually a full ring of nonmetallic material, located and retained in the nut at its top surface. These are designated as property grade NE2, NE5, and NE8 meeting the mechanical and performance requirements of Table 2 or 3.
6 WIDTH ACROSS FLATS
The width across flats shall be the distance measured perpendicular to the axis of the nut between two opposite wrenching flats.
7 CORNER FILL
A rounding or lack of fill at the junction of hex cornerswith the chamfer shall be permissible, provided thewidth across corners is within specified limits at andbeyond a distance equal to 17.5% of the nominal threaddiameter from the chamfered face.
HEIGHT
The locknut height shall be the overall distance, mea-sured parallel to the axis of the locknut, from the top ofthe locknut to the bearing surface.
