F Grade 55 Threaded Rod is manufactured from high strength, low alloy, 55 ksi yield strength steel. The F Specification is designed to cover Threaded. ASTM F is the standard specification for straight and bent, headed and Grade 55 – anchor bolts manufactured from modified mild steel with higher. The specification for ASTM F covers straight and bent, headed and headless, F Grade 55, High strength, low alloy, 55 ksi yield steel anchor bolts.

Grade 55 is more elastic and gf at a lower cost, rendering it more applicable for general construction needs, while B7 is heat treated and contains alloys that make it more suitable for corrosive environments.
They are both heat treated parts with asmt identical mechanical and chemical requirements. Grade 55 round bar is not commonly available through local warehouses.
We would like to congratula… https: The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for three specimens, with no one specimen falling below 12ft-lbs. Supplementary requirements shall apply only when specified in the purchase order or contract.
ASTM F Grade 55 vs ASTM A B7 – All America Threaded Products
Galvanizing F grade 55 anchor bolts can be provided in either a black or galvanized condition. If the application allows for a straight bolt, then B7 can be considered as a substitute for F Grade If S1 is not specified by the purchaser, the Grade 55 material may or may not be weldable.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This specification covers the chemical, mechanical, and dimensional requirements, and associated test methods for straight and bent, headed and headless anchor bolts also known as anchor rods 5 of carbon, carbon boron, alloy, or high-strength low-alloy steel and having specified yield strengths.
Portland Bolt buys mill runs of round bar and stocks this material for immediate processing.
We offer a wide selection of materials, finishes, and sizes of Figure U-Bolts. Leave a Comment Cancel reply Your email address will not be published. The purchaser can specify supplemental requirement S1 which requires weldability through chemical composition restrictions and by a carbon equivalency formula. The three grades 36, 55, and designate the minimum yield strength ksi of the anchor bolt.
We are a prime U. Contrary to 555 belief, not all grade 55 material is weldable. Through chemical composition restrictions and by a carbon equivalency formula, S1 provides assurance of weldability. Though relevant for many construction applications and certainly more cost-effective than B7, Grade 55 is still a specialty d1554 that few manufacturers or distributors supply. This specification was widely used in the light pole and traffic signal industry long before the ASTM F specification was introduced in and was commonly referred to as A36M This increased elasticity means that Grade 55 is most frequently used in the construction industry, as buildings and other infrastructure naturally experience displacement over atsm.
The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for axtm specimens, with no one specimen falling below 12ft-lbs.
Stamping of F bolts with manufacturer’s identification is a supplemental requirement S2 Color coding is required unless the grade is stamped in accordance with supplemental requirement S3.
For additional compatible nuts see the Nut Compatibility Chart. Supplementary Testing The following supplemental requirements apply to F Grade F anchor bolts can take the form of either headed bolts, straight rods, or bent anchor bolts. By Dave Singer 0 comment.
Supplementary requirements shall apply only when specified in the purchase order or contract. Weldable version of the Grade 55 specification.
The anchor bolts shall also meet specified values for nominal size, body diameter, bend section, length, bend angle, and coated length. Link to Active This link will always route to the current Active version of the standard. F Grades F Grade 36 Low carbon, 36 ksi yield steel anchor bolts F Grade 55 High strength, low alloy, 55 ksi yield steel anchor bolts F Grade Alloy, heat treated, high strength ksi yield steel anchor bolts.
Be skeptical of fastener distributors and manufacturers with limited manufacturing capabilities who attempt to substitute round bar or even A grade B7 material for F grade Materials In the latest installment of our Threaded series, …. References to anchor bolts in this standard do not necessarily exclude all-thread rod. When S1 is not specified, the Grade 55 material may or may not be weldable.
F1554 Grade 55
Instead of the standard color coding of yellow spray paint to indicate Grade 55, supplemental requirement S3 can be specified by the purchaser to have a permanent grade identification on the end of the anchor bolt that projects from the concrete.
In this series, we will be covering four common topics to help you build the foundation you need to better understand the threaded fastener industry. Please describe your threaded product needs with as much detail as possible and we will consult you on what will most benefit your objectives. V1554 following supplemental requirements apply to F Grade Permanent manufacturer and grade marking f5154 allowed under the S2 supplementary requirements.
