Q: What is the difference between ASTM A325 and A490 bolts?
A: ASTM A490 bolts are made of higher-strength alloy steel with a minimum tensile strength of 150 ksi, compared to A325 bolts, which have lower tensile strength, making A490 suitable for heavy structural applications.
Q: Can these bolts be used outdoors?
A: Yes, with hot-dip galvanized or other protective coatings, they are suitable for outdoor and industrial environments.
Q: Are custom lengths and diameters available?
A: Yes, we supply custom sizes to meet specific project requirements.
Q: What tools are required for installation?
A: Standard hex wrenches or socket tools are used for installation, following ASTM-approved torque specifications.
