ASTM 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.
