FAQs
Q1: What is the difference between high-strength bolts and common bolts?
High-strength bolts are heat-treated to achieve higher tensile strength and are used in structural load-bearing connections.
Q2: Do high-strength bolts require special installation?
Yes, they require controlled tightening torque to achieve proper preload performance.
Q3: Can bolts be supplied as a complete set?
Yes, bolts can be supplied with matching nuts and washers.
Q4: What affects bolt performance in structures?
Material grade, installation torque, and surface treatment all affect performance.
Q5: Are they suitable for outdoor structures?
Yes, galvanized or coated versions are suitable for outdoor and corrosive environments.
