Grades of Swedged Anchor Rods

The most common swedged anchor rod specifications called out are F1554 Grade 36, 55, and 105. You may see this called out as AASHTO M-314 as well. We can also swedge A307, A449, A354, A193, A320, F593, and A36 materials. 

ASTM Specifications

	F1554	ASTM F1554 is the widely used specification for anchor bolts, including grades 36, 55, and 105, corresponding to their minimum yield strength.
	A307	The Grade C specification previously covered anchor bolts but was replaced by Grade 36 in document F1554 in 2007. While Grades A and B could theoretically be used as anchor bolts, they are not technically anchor bolt specifications. For mild steel anchor bolts with similar chemical and strength requirements, Grade 36 in document F1554 should be considered.
	A449	This spec is a medium-strength bolt grade that has been heat-treated for durability. It is made from medium carbon or alloy steel and is commonly used for various purposes, including anchor bolts.
	A325	This is a tempered and quenched bolt made from alloy steel and heat-treated to the required strength. There are 2 grades, BC and BD. As the high tensile strength makes it more susceptible to hydrogen embrittlement, ASTM recommends against galvanizing Grade BD.
	A193	This specification was designed for low-temperature service. The most common grades used for anchor bolts are the high-strength alloy steel grade L7 and the stainless steel grades B8 and B8M. Grade L7 anchor bolts require a Charpy test at -150 degrees Fahrenheit.
	A320	This specification was designed for low temperature service. The most common grades used for anchor bolts are the high strength alloy steel grade L7 and the stainless steel grades B8 and B8M. Grade L7 anchor bolts require a Charpy test at -150 degrees Fahrenheit.
	F2329	This ASTM specification covers the hot-dip galvanizing of bolts, nuts, washers, and other threaded parts. Galvanizing was previously covered under ASTM A153 but has been more defined under F2329.
