What are ASTM A325 bolts?
ASTM A325 Hex Bolts fasteners used in a variety of industrial applications. The fasteners' finishes vary, and ASME SA325 Type 1 Heavy Hex Structural Bolts can be galvanised as one finish. Galvanising adds a corrosion layer protection to hex bolts. ASTM A325 Type 3 Stud Bolts are part of a standard for high tensile strength hex bolts.
Difference between ASTM A325 Type 1, Type 2, and Type 3
They can be treated by heat and available in various styles, including ASTM A325 flanged bolts and others. The diameter of these bolts varies from 0.5 inches to 1.5 inches. The material is quite strong. ASTM A325 Bolts Type 1 have a minimum tensile strength of 830MPa and a yield strength of 660MPa. These levels are nearly three times higher than conventional steel grades.
For type 1 bolts, A325 Hot Dip Galvanised Threaded Rod can be constructed of carbon alloy steel. Type 2 bolts are produced from low carbon steel. A325 fully threaded bolts and nuts are also available in weathering steel. When damaged, type 3 self-heals to generate a layer of oxide that prevents oxidation. The A325 bolts help to keep the application's surface smooth.
ASTM A325 structural bolts vs high tensile bolts
When it comes to mechanical bolting projects, strength is everything. There are many more similarities than differences between ASTM A325 Fastener and ASTM A325 Washer.
The two designations' overall features and physical and chemical strengths are almost identical. The distinctions may be noted in their categories and the sorts of jobs indicated for each bolt.
ASME SA325 High Strength Bolts for structural steel connections in big building projects. SAE grade 5 bolts, on the other hand, are commonly used in OEM-type applications.

The stress area is calculated as follows:
As = 0.7854 [D-(0.9743/n)]
- As = stress area, in2,
- D = nominal bolt size
- n = threads per inches
