ASTM F468 Bolts

ASTM F468M specification also known as metric specification for ASTM F46 which covers the requirements for commercial wrought nonferrous Bolts, Screws, Threaded Rod and Studs in nominal thread diameters M6 to M36, whereas ASTM F468 specification covers the imperial (inch) standard requirements for commercial wrought nonferrous Bolting in nominal thread diameters ¼” to 4” inclusive in a number of alloys in common use and intended for general service applications. In general these Bolts are used with Hex Nuts and Heavy hex Nuts as per ASTM F467 / F467M Specification.

A Where both tension and hardness tests are performed, the tension tests shall take precedence for acceptance purposes. For aluminum and titanium alloys, hardness tests are for information only. See 6.4.

B The yield and tensile strength values forfull-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 areas.

C Yield strength is the stress at which an offset of 0.2 % gage length occurs.

D Elongation is determined using a gage length of 4 diameters of test specimen in accordance with Test Methods E 8.

E“HF” denotes 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.

HTi 5 Class A requires wedge tensile testing in accordance with 6.5. Ti 5 Class B requires wedge tensile testing in accordance with 6.5.1.
