This specification, however, does not cover the requirements for mechanical expansion anchors, powder-activated nails or studs, and anchor bolts fabricated from deformed bars. The bolts shall adhere to specified elemental chemical compositions as examined by heat and product analysis. They shall also be tested for their conformance with mechanical properties such as tensile strength, yield strength, elongation, reduction of area, and stress area. The anchor bolts shall also meet specified values for nominal size, body diameter, bend section, length, bend angle, and coated length.
SCOPE
1.1 This specification covers straight, bent, headed, and headless anchor bolts (also known as anchor rods) made of carbon, medium carbon boron, alloy, or high-strength low-alloy steel. It provides for anchor bolts in three strength grades, two thread classes, and in the diameters specified in Section 4. The specification also covers all-thread rod for use in anchoring to concrete. References to anchor bolts in this standard do not necessarily exclude all-thread rod.  
1.2 Anchor bolts are intended for anchoring structural supports to concrete foundations. Such structural supports include building columns, column supports for highway signs, street lighting and traffic signals, steel bearing plates, and similar applications.  
1.3 Supplementary requirements are included to provide for Grade 55 weldable steel, permanent manufacturers and grade identification, and impact properties for Grades 55 and 105.  
1.4 Zinc coating requirements are in Section 7.  
1.5 Suitable nuts and washers are listed in 6.7. Washers are detailed in 6.8.  
1.6 This specification does not cover mechanical expansion anchors, powder-activated nails or studs, or anchor bolts fabricated from deformed bar.  
1.7 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.  
1.8 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.

Standard Specification for Alloy Steel Eyebolts

ABSTRACT
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.
