ABSTRACT
This specification covers two types of quenched and tempered, steel, metric heavy hex structural bolts. The bolts are intended for use in structural connections. The bolts are furnished in sizes M12 to M36 inclusive. They are designated by type denoting chemical composition as follows: Type 1—Medium-carbon, carbon boron, medium carbon alloy, or alloy boron steel; and Type 3—Weathering Steel. Materials shall be tested and the individual grades shall conform to specified values of heat treatment, threading, hot-dip and mechanically coated zinc coatings, lubrication, secondary processing, chemical composition, mechanical properties such as hardness, tensile properties, and rotational capacity.
WITHDRAWN RATIONALE
This specification covers two types of quenched and tempered steel heavy hex structural bolts having a minimum tensile strength of 120 ksi for sizes 1.0 in. and less and 105 ksi for sizes over 1.0 to 11/2 in., inclusive.
Formerly under the jurisdiction of Committee F16 on Fasteners, this specification was withdrawn in May 2016 and replaced by Specification F3125/F3125M for High Strength Structural Bolts, Steel and Alloy Steel, Heat Treated, 120 ksi (830 MPa) and 150 ksi (1040 MPa) Minimum Tensile Strength, Inch and Metric Dimensions. Specification F3125/F3125M supersedes and replaces specifications; A325, A325M, A490, A490M, F1852 and F2280. The unified Specification F3125/F3125M corrects known inconsistencies in the original documents and the combination will assure that requirements of the products covered under the original standards stay aligned.

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.
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.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
