ASTM F541-12

1.1 This specification covers forged, quenched and tempered, alloy steel threaded eyebolts with improved toughness properties and intended primarily for low temperature applications. The eyebolts are chemically and metallurgically constituted to produce a low transition temperature to minimize brittle failure. Maximum thread size is 2.500 in. (63.50 mm).

1.2 The eyebolts are furnished in two types, as follows:

1.2.1 Type 1 – Straight Shank Eyebolt.

1.2.2 Type 2 – Shoulder Eyebolt.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information only.
