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.
Materials In the latest installment of our Threaded series, …. Contrary to popular belief, not all grade 55 material is weldable. Portland Bolt buys mill runs of round bar and stocks this material for immediate processing. If S1 is not specified by the purchaser, the Grade 55 material may or may not be weldable.
Link to Active This link will always route to the current Active version of the standard. Grade 55 round bar is not commonly available through local warehouses. On the other hand, B7 is heat treated, increasing strength but rendering the material more brittle. Applications for F anchor bolts include columns in structural steel framed buildings, traffic signal and street lighting poles, and overhead highway sign structures to name just a few.
In the latest installment of our Threaded series, we discuss threaded rod finishes and identify which work best for certain applications. Washers are detailed in 6. Material Substitution 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 We offer a wide selection of materials, finishes, and sizes of Figure U-Bolts.
Permanent manufacturer and grade marking is allowed under the S2 supplementary requirements.
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. Permanent grade identification on the end of the anchor bolt that projects from the concrete, in lieu of color coding. This specification was widely used in the light pole atm traffic signal industry long before the ASTM F specification was introduced in and was commonly referred to as A36M Supplementary Testing The following supplemental requirements apply to F Grade 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. This field should be left blank. This specification covers the chemical, mechanical, and dimensional requirements, and associated test methods for straight and bent, headed and headless anchor bolts also known f154 anchor rods made of carbon, carbon boron, alloy, or high-strength low-alloy steel and having specified yield strengths.
The following supplemental requirements apply to F Grade Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Through chemical composition restrictions and by a carbon equivalency formula, S1 provides assurance of weldability.
F Grade 55 – F Anchor Bolts
Your email address will not be published. The anchor bolts are furnished fr three strength grades, two thread classes, and various sizes, and are intended for anchoring structural supports to concrete foundations such as building columns, column supports for highway signs, street lighting and traffic signals, steel bearing plates, and similar applications. Historical Version s – view previous versions of standard. Be skeptical of fastener ast, and manufacturers with limited manufacturing capabilities who attempt to substitute round bar or even A grade B7 material for F grade In the latest installment of our Threaded series, we discuss materials used to make threaded rod and which work best for certain applications.
This abstract is a brief summary of the referenced standard. Color coding on the end — 36 blue, 55 yellow, and red — helps facilitate easy identification in the field. F anchor bolts can take the form of either headed bolts, straight rods, or bent anchor bolts. The ASTM Zstm specification was introduced in and covers anchor bolts designed to anchor structural supports to concrete foundations.
ASTM F grade 55 anchor grr are manufactured from a modified mild steel that has a higher minimum yield strength 55 ksi than traditional A36 mild steel 36 ksi. By Dave Singer 0 comment.
ASTM F – 18 Standard Specification for Anchor Bolts, Steel, 36, 55, and ksi Yield Strength
In addition to standard round be… https: 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 specification also covers all-thread rod for use in anchoring to concrete. For additional compatible nuts see the Nut Compatibility Sstm.
Grade 55 is more elastic and available 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.

F1554 Grade 55
Overview ASTM F grade 55 anchor bolts are manufactured from a modified mild steel that has a asttm minimum yield strength 55 ksi than traditional A36 mild steel 36 ksi. The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for three specimens, with no one specimen falling below 12ft-lbs.
Such structural supports include building columns, column supports for highway signs, street lighting and traffic signals, steel bearing plates, and similar applications.
It provides for anchor bolts in three strength grades, two thread classes, t1554 in the diameters specified in Section 4.
They shall also be tested for their conformance with mechanical properties such as tensile strength, yield strength, elongation, reduction of area, and stress area.
