ASTM F901-20

Standard Specification for Aluminum Transmission Tower Bolts and Nuts

ABSTRACT
This specification covers aluminum transmission tower bolts and nuts. Bolts shall be manufactured from alloy 2024 and nuts from alloy 6061 or 6262, and shall be cold formed, hot formed, or machined formed. Alloy materials for bolts and nuts shall conform to the chemical requirements of this specification. Bolts and nuts shall conform to the required tensile strength, dimensions, workmanship, finish, appearance, marking, packaging, and shipping. Test methods shall include chemical analysis, wedge tension test, shear test, and proof-stress test.
SCOPE
1.1 This specification covers aluminum structural bolts and nuts for use in the construction of aluminum transmission towers, substations, and similar aluminum structures.  
1.2 Diameters of bolts and nuts furnished to this specification are 5/8 , 3/4 , and 7/8 in.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
