This specification covers requirements for commercial wrought non ferrous bolts, hex cap screws and stud bolts 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 F468 and F468M with coarse and fine threads. All the bolt and screw products are duly tested and supplied with EN 10204 Type 3.1 certification.

A Elements shown as balance shall be arithmetically computed by deducting the sum of the other named elements from 100.
B Cobalt is to be counted as nickel.
C Alloy 625 material shall be refined using the electrostag remelting process (ESR), or the vacuum arc remelting process (VAR).

A where both tension and hardness tests are performed, the tension tests shall take precedence for acceptance purposes. For alumium and titanium alloys, hardness tests are for information only.
B The yield tensile strength values for full size products shall be computed by dividing the yield and maximum tensile load by the stress area for the product diameter and thread pitch as given in table on tensile stress areads.
C Yield strength is the stress at which an offset of 0.2% gauge length occurs.
D Elongation is determined using a gauge length of 4 diameters of test specimen in accordance with Test Methods E8.
E "HF" denoted a hot formed product
F Aluminum alloy temper designations are in accordance with ANSI H35.1.
G Full size test mechanical properties apply to fasteners with a maximum diameter of 76 mm. Mechanical properties of larger sections shall be negotiated between the material manufacturer and the fastener producer.
H Ti 5 Class A requires wedge test tensile testing in accordance with section 6.6 & Ti 5.5 Class B requires wedge tensile testing in accordance with section 6.5.1 of ASTM F468.
