Abrasive and Fastening Solutions Inc. is a proud manufacturer of ASTM F1554 Grade 55 Bent Anchor Bolts. Using materials made and melted in the United States of America to offer the finest quality bars. F1554 Grade 55 steel bar is a designed strength, low to medium carbon content grade. It has a 55 ksi yield strength which is required by the F1554 specification for anchor bolt and fastener applications. While Bent Anchor Bolts are not as popular to the rise in demand for a straight anchor rod, there are many applications and parts of the country that still utilize the bent anchor bolt.
ASTM International is one of the largest voluntary standards developing organizations in the world. They are a not-for-profit organization that provides a forum for the development and publication of international voluntary consensus standards for materials, products, systems and services.
Bent Anchor Bolts are made with a 90 degree bend at the end of the rod used as the anchor point in concrete for a cast in place anchor. Using this method can alleviate the use of a nut and or plate washer on the bottom of a Double End Anchor Rod.
Our Bent Anchor Bolts are made using a roll threading machine. Rolled threads are formed by pressing threading dies into the shank to displace the surplus of the metal outward. The original rod diameter must be slightly less than the nominal diameter, although the root area will still be critical, unless the rod end is upset. The steel is cold-worked, compressing its grain and increasing the yield and tensile strength, generally from 10 to 30 percent. Roll threading is the most productive manner in manufacturing Bent Anchor Bolts.
With over twenty years of experience in supplying Bent Anchor Bolts to the steel construction industry, we at Abrasive and Fastening Solutions take great pride in providing the highest quality products manufactured in the USA in today’s market. All of our Bent Anchor Bolts are made to order and we are especially proud of our ability to meet our customers needs on a daily basis. While we offer an array of different products and configurations, if you don’t see what you are looking for, please call us to discuss and we will do our best to assist you in what you need.
Substituting Grade 36 with Grade 55
Customers should be aware that we do not carry Grade 36 anchor bolts and rods. Instead, when they are asked for, we provide as a substitute Grade 55 anchor bolts. Grade 55 bolts are of a higher quality and feature stronger material. Moreover, they cost the same as the 36 Grade bolts. The fact that they are stronger means that the Grade 55 bolts can more then adequately perform in applications that calls for the use of Grade 36 bolts. The substitution of the Grade 36 bolts are within the guidelines of the ASTM F1554 Anchor Bolt Specification that we are required to follow when producing Anchor bolts and rods.
As all of you are probably aware, the ASTM F1554 Anchor Bolt Specification covers straight and bent headless, carbon steel, stainless steel, and high-strength low alloy steel anchor bolts. According to the specification, anchor bolts are furnished in three strength grades –- 36, 55, and 105. The grades refer to the minimum yield strength of the bolts. Grade 36 is the lowest grade of steel. Grade 105 is the strongest grade. The ASTM Specification permits the substitution of Grade 55 for Grade 36 as long as the grade 55 material meets the S1 supplement requirement of weldability.
Abrasive & Fastening Solutions is supplying the strongest material available at the same price as the lower grade option. We find that manufacturing only Grade 55 and 105 anchor bolts allows us the opportunity to provide to you the best products at the most competitive cost.
