Description / Abstract:
Type:
This specification establishes the requirements for the
following types of self-locking nuts in thread diameter sizes
0.1380 through 0.6250 inches:
a. Wrenching Nuts: i.e., hexagon, double hexagon and spline
nuts.
b. Anchor Nuts: i.e., plate nuts, gang channel nuts, and shank
nuts.
The wrenching nuts, shank nuts, and nut elements of plate and
gang channel nuts are made of a corrosion and heat resistant
nickel-base alloy of the type identified under the Unified
Numbering System as UNS N07001 and of 180,000 psi axial tensile
strength at room temperature, with maximum conditioning of parts at
1400 °F prior to room temperature testing.
Application:
Primarily for use in aerospace propulsion systems up to
approximately 1400 °F for tension height nuts made from bar,
forging, or sheet. Nuts are designed for use with bolts capable of
developing 180,000 psi tensile strength at room temperature and
having UNJ profile threads.
