Frequently asked question (FAQ)

Question: What does the "8-Mark" on the bolt head indicate?
Answer: The 8-Mark signifies a strength classification of 8T, meaning the bolt has a minimum tensile strength of 80 kgf/mm², ensuring high load-bearing capacity.
Question: Why is a high-tensile bolt necessary for certain applications?
Answer: High-tensile bolts like this one can withstand greater forces, making them essential for:
•Heavy machinery and structural assemblies
•Automotive and aerospace applications
•High-load industrial equipment
Question: How does the tensile strength compare to standard bolts?
Answer: An 8T-rated bolt is significantly stronger than a standard Grade 4.6 or 5.8 bolt, offering higher load-bearing capacity and durability.
Question: How do I prevent galling when tightening these bolts?
Answer: To prevent galling:
•Use proper lubrication (e.g., anti-seize compounds).
•Tighten bolts slowly and evenly to reduce heat buildup.
•Avoid over-tightening, which may cause thread damage.
