What does the '8-Mark' on the bolt head indicate?

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.

Why is a high-tensile bolt necessary for certain applications?

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

How does the tensile strength compare to standard bolts?

An 8T-rated bolt is significantly stronger than a standard Grade 4.6 or 5.8 bolt, offering higher load-bearing capacity and durability.

How do I prevent galling when tightening these bolts?

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.
