This specification covers the basic requirements and corresponding test methods for forged, quenched, and tempered, alloy steel threaded eyebolts with improved toughness properties and that are chemically and metallurgically constituted to produce a low transition temperature to minimize brittle failure, intended primarily for low temperature applications. The eyebolts are furnished either as straight shank eyebolts (Type 1), or shoulder eyebolts (Type 2). Sampled specimens shall be tested, and conform accordingly to chemical (carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum, and nickel), metallurgical (grain size, decarburization, and macrotech properties), and mechanical (Brinell hardness, tensile strength, breaking strength, proof load, impact strength, and bend strength) requirements.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
