  • Alternatives - ASTM A354
    ASTM A490 was withdrawn in 2016, and A490 is currently a grade which falls under the F3125 specification Bolts manufactured under this specification are intended for use in structural connections
  • ASTM A354 - Portland Bolt
    Grade BD bolts are higher in strength than grade BC, and equal in strength to ASTM F3125 grade A490 bolts Unlike A490 however, the A354 standard is unrestricted in its configuration
  • Use of A354 bolts instead of A325 A490 for slip critical
    According to ASTM A354 it specifies grade BD as an acceptable substitute for A490 fasteners over 1-1 2” in diameter or with nonstandard thread lengths A490 and grade BD have identical minimum tensile and yield properties
  • Bolt Grades | Steel Calculator
    Mechanical properties for ASTM and metric ISO 898-1 structural bolt grades Includes Fy, Fu, AISC minimum pretension (Table J3 1), and nominal shear strength (Table J3 2)
  • Bolt Torque Chart - Portland Bolt
    Clamp loads are based on 75% of the minimum proof loads for each grade and size Proof load, stress area, yield strength, and other data is based on IFI 7th Edition (2003) Technical Data N-68, SAE J429, ASTM A307, A325, A354, A449, and A490
  • Is A354BD an Acceptable Substitution for A490? - ASTM A354
    F3125 A490 is a specification for heavy hex bolts intended for structural connections The specification only covers heavy hex bolts up to 1-1 2” diameter In situations where bolts other than that configuration, or bolts larger than 1-1 2” diameter are required, A354 Grade BD may be specified
  • Grades - Anchor Rods
    It is virtually identical to the A490 specification in chemical and mechanical properties However, it does not have the configuration limitations that A490 has If you have a project with A490 anchor rods specified, you should ask the Engineer of Record to consider A354 Grade BD in its place
  • 6. 2. Ordering Bolts - aisc. org
    No, it is not acceptable to substitute SAE J429 Grades 5 and 8 bolts for ASTM F3125 Grades A325 and A490 bolts, respectively The strength properties of SAE J429 Grade 5 bolts and Grade A325 bolts are identical; likewise, SAE J429 Grade 8 bolts are the strength equivalent of Grade A490 bolts
  • Grades of Bolts - Bolt Grade Marking Chart | AFT Fasteners
    These charts helps to identify the grades of bolts using the identification marks on the bolt's head along with the strength and hardness of common grade bolts Please note the bolt heads may also include the manufacturer's identification stamp, especially with high strength bolts
