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.
