A325s have a heavy hex head, a full body diameter, and are normally short in overall length since they are connecting steel to steel. Unlike other ASTM grades, A325 is specific not only in the chemical and mechanical requirements, but also in the allowed configuration. These bolts range in diameter from 1/2 through 1-1/2 and are manufactured from a medium-carbon or medium-carbon alloy steel that is ASTM F3125 A New Bolt Standard CISC-ICCAIgnoring the strength increase in large A325 and F1852 bolts is a safe and conservative interim solution. CSA S16-14 . S16-14 adopted the tensile strength, F u, and minimum pretension forces for bolts in ASTM bolt standards prior to publication of F3125 and values for F u are explicitly stated in S16-14 Standard. Therefore, the strength
ASTM A325 (F3125) Structural bolts, steel, heat treated, 120/105 ksi minimum tensile strength. The ASTM A325 specification covers high strength heavy hex structural bolts from 1/2 diameter through 1-1/2 diameter. These bolts are intended for use in structural connections and therefore have shorter thread lengths than standard hex bolts.

The most common heavy hex head screw, these steel screws meet ASTM A325 regulations for structural joints, such as mating I-beams and scaffolding. Material meets ASTM F3125 specifications for quality. Dimensions meet ASME B18.2. 6 specifications. Length is measured from under the head.. Partially threaded screws come with precise threaded and unthreaded portions, allowing you to place only the Grades of Bolts - The Home DepotGrade A325 . This bolt is an ASTM specification bolt thats readily available in many home improvement and automotive stores. Its virtually identical in terms of chemical and physical strengths and properties as an SAE Grade 5 bolt. Head Marking:A325; Material:Carbon or Alloy Steel with or without Boron; Size Range:1/2-inch to 1-1/2-inch Hardware ASTM A325 - A325 Structural Bolts ASTM A325The recommended grade of nut for an ASTM A325 structural bolt is ASTM A563 Grade D, DH, or C. ASTM A194 2H is also an acceptable substitute. These ASTM grades are all high strength and go through a heat treating process required to develop their mechanical characteristics.

ASTM A325 and ASTM A490 are the two U.S. standard structural bolts. When looking at the mechanical requirements of bolts it appears that an ASTM A325 and SAE J429 Grade 5 are identical as do the ASTM A490 and the SAE J429 Grade 8. This begs the question, Can an SAE J429 Grade 5 be used when an ASTM A325 is specified? The answer is The Difference Between F3125 A325 and F3125 A490 Jan 09, 2018 · Authors Note:In 2016, ASTM A325 and A490 were replaced by ASTM F3125. A325 and A490 are now grades under the F3125 specification. When reading this blog, please note that when we discuss A325 and A490 structural bolts, we are specifically discussing the grades of F3125 structural bolts. What Are the Different Grades of Bolts? HunkerIts strength grades are indicated by the letter A plus three numerals stamped on the bolt head. Common ASTM grades include A307, which roughly corresponds to SAE Grade 2. An ASTM A325 bolt is roughly equivalent in strength to SAE Grade 5 and an A490 bolt is about equivalent in strength to SAE Grade 8.
Jul 06, 2010 · ASTM A325 bolts are more commonly specified by engineers for use in structural steel connections on heavy construction projects, while SAE Grade 5 bolts are more common in OEM-type applications. Grade 5 bolts are most typically made, and are most readily available in a finished hex bolt configuration. A325 bolts are required to have a heavy hex head. The same thing applies for the
