ASTM F3125

Gr. A325

ASTM F3125 Grade A325 fasteners are high-strength structural bolts designed for heavy-duty applications in construction and engineering. Known for their durability and reliability, these bolts provide a secure and robust connection in structural steel joints. With stringent manufacturing standards, Grade A325 bolts offer exceptional tensile strength of up to 120 ksi and weather resistance*. Ideal for use in critical structural elements, they ensure the integrity and safety of constructions.

*For Weather resistance, see Type 3 products
** Please take note that Boulons Plus only sell pre-assembled sets including 1 bolt, 1 washer and 1 nut.

Gr.A325 Specifications

Facilitating the selection of bolt length for a specific grip and bolt diameter is simplified by referring to the “Bolt Lengths for Various Grips” chart on page 6-167 in the Handbook of Steel Construction, 11th edition. This chart is relevant to the Imperial Series of ASTM F3125/F3125M bolts, including Grades A325/F1852 and A490/F2280 high-strength bolts used in bearing-type and slip-critical connections. It’s important to note that the provided bolt lengths may not automatically exclude bolt threads from the shear plane(s).

As per Section 16 of ASTM F3125/F3125-23, here’s a summary of the requirements for packaging and package marking of heavy hex bolts and twist-off bolt assemblies.

16. Packaging and Package Marking:

16.1 Packaging:

Packaging should adhere to the manufacturer’s standard practices or as mutually agreed upon by the purchaser and supplier.
Matched assembly lot components, tested for rotational capacity, should be shipped together when feasible. Component packages must be clearly identified with assembly lot numbers for proper matching and assembly in the field.
Heavy Hex Bolt assemblies must include at least one Heavy Hex Bolt and a suitable Heavy Hex Nut, or a Heavy Hex Bolt, Heavy Hex Nut, and at least one Hardened Washer, meeting specified requirements.
Twist-Off Bolt assemblies should consist of a bolt with a spline end, a suitable Heavy Hex Nut, and at least one Hardened Washer, all meeting specified standards. Twist-Off style bolts are required to be packaged, certified, and installed as matched assemblies.
Special packaging or labeling requirements should be defined during the inquiry and reiterated at the time of the order.

16.2 Package Marking:

Each shipping unit must be clearly marked with the following information:

- ASTM designation, Grade, Type, and Style.
- Size of the components.
- Name of the manufacturer or responsible party.
- Number of pieces in the unit.
- Lot number, with shipping units marked accordingly.
- Purchase order number or other distinguishing information, if required by the customer.
- Country of origin, if required by the customer.

^A The stress area is calculated as follows for inch: AS = 0.7854 [D – (0.9743/n)]2; for Metric: AS = 0.7854 (D – 0.9382P)2; where AS = Stress Area, D = Nominal Bolt Size, and P = thread pitch.

^B Previous versions of ASTM A325 and F1852 required tensile testing based on 105 ksi min. tensile strength for larger diameters, and proof load testing of 74 ksi (length measurement method) and 81 ksi (yield strength method). This specification was changed to align with AISC/RCSC design and installation values and metric equivalent strength levels.

As per Section 16 of ASTM F3125/F3125-23, here’s a summary of the requirements for packaging and package marking of heavy hex bolts and twist-off bolt assemblies.

16. Packaging and Package Marking:

16.1 Packaging:

Packaging should adhere to the manufacturer’s standard practices or as mutually agreed upon by the purchaser and supplier.
Matched assembly lot components, tested for rotational capacity, should be shipped together when feasible. Component packages must be clearly identified with assembly lot numbers for proper matching and assembly in the field.
Heavy Hex Bolt assemblies must include at least one Heavy Hex Bolt and a suitable Heavy Hex Nut, or a Heavy Hex Bolt, Heavy Hex Nut, and at least one Hardened Washer, meeting specified requirements.
Twist-Off Bolt assemblies should consist of a bolt with a spline end, a suitable Heavy Hex Nut, and at least one Hardened Washer, all meeting specified standards. Twist-Off style bolts are required to be packaged, certified, and installed as matched assemblies.
Special packaging or labeling requirements should be defined during the inquiry and reiterated at the time of the order.

16.2 Package Marking:

Each shipping unit must be clearly marked with the following information:

- ASTM designation, Grade, Type, and Style.
- Size of the components.
- Name of the manufacturer or responsible party.
- Number of pieces in the unit.
- Lot number, with shipping units marked accordingly.
- Purchase order number or other distinguishing information, if required by the customer.
- Country of origin, if required by the customer.
