Description
ASTM F3125M – ASTM A325M Heavy Hex Bolt
ASTM F3125M – ASTM A325M is an ASTM International standard specifically tailored for heavy hex structural bolts. Titled the “Standard Specification for Structural Bolt, Generally Steel, Heat Treated,” it ensures a minimum tensile strength of 800/830 N/mm² (Megapascal) for optimal structural integrity. This standard delineates mechanical properties for bolts ranging from M10 to M56 in size.
In brief, ASTM F3125M – ASTM A325M refers to Heavy Hex Structural Bolting Assemblies in the metric system. It encompasses A325M Bolts, A563M Nuts, and F436M Washers, ensuring comprehensive compatibility and reliability in structural applications.
General:
In brief, Type 3 Grade F3125 bolts are distinguished by the marking “A325M” to set them apart from standard Grade A325s. Additionally, Grade A490 bolts are available in diameters ranging from 1/2 to 1-1/2 inches with a minimum tensile strength of 150,000 PSI for all diameters, and they come in two types.
In fact, ASTM A325M is an ASTM International standard for heavy hex structural bolts, officially titled the Standard Specification for Structural Bolts, Steel, Heat Treated, with a minimum tensile strength of 120/105 ksi. This standard defines mechanical properties for bolts ranging from 1⁄2 to 1 1⁄2 inches (13 to 38 mm) in diameter.
According to ASTM A325 specifications, all threaded components of the fastener assembly must undergo galvanization by the same process. The supplier’s option is limited to one process per item, with no mixed processes allowed within a lot.
General Overview
Type 1 Grade F3125 bolts are marked with “A325M” to distinguish them from standard Grade A325 bolts. Additionally, Grade A490 bolts are available in diameters from 1/2″ to 1-1/2″, with a minimum tensile strength of 150,000 PSI for all sizes. These bolts are offered in two types.
ASTM A325 is another ASTM International standard for heavy hex structural bolts, officially called the “Standard Specification for Structural Bolts, Steel, Heat Treated”. It requires a minimum tensile strength of 120/105 ksi, with bolts ranging in diameter from 1/2″ to 1 1/2″ (13 to 38 mm).
Galvanization Requirements
According to ASTM A325M specifications, all threaded components of the fastener assembly must undergo galvanization using the same process. The supplier can choose only one process per item, with no mixing of processes within a lot.
