ASTM F467 Specification for Non Ferrous Nuts

ASTM F467 / F467 - Standard Specification for Non Ferrous Nuts for General Application.

This specification covers requirements for commercial wrought non ferrous nuts from diameter 1/4 inch to 1-1/2 inch inclusive manufactured from variety of Copper alloys, Monel alloy 400, 405, K500, Inconel 625, Aluminum alloys and Titanium as well, intended for general service applications. BoltPort manufactures most of the alloy bolting cover under ASTM F467(Imperial) and F4677(Metric) with coarse and fine threads. All the bolt and screw products are duly tested and supplied with EN 10204 Type 3.1 certification.

A All reported values are maximums, unless a range is specified.
B A residual is an element present in a metal or an alloy in small quantities inherent to the manufacturing process but not added intentionally. Residual elements need not be reported unless a report is specially required by the purchaser.
C Identical chemical requirements apply to both Class A and B as defined in Table 2 and 6.5 of ASTM F467.
D Ruthenium and palladium, or both, may be added to Grade 19 for enhanced corrosion resistance as negotiated between purchaser and vendor. Chemical analysis is not required unless specifically required by the purchaser.

A Tensile stress areas are computed using the following formula: As = 0.7854 [D- (0.9743/n)]2
Where:
As = Tensile stress area, in.2,
D = Nominal size (basic major diameter), in., and,
n = number of threads per inch.
