About Hitentichil grade bolt

The term "Hitensile" is a common industry shorthand for "High Tensile," which refers to bolts designed to withstand high levels of tension and heavy loads. These are superior in strength to standard bolts and are used in critical, high-stress applications.

Key characteristics

Material: High tensile bolts are typically made from medium carbon steel or alloy steel that is heat-treated through a process of quenching and tempering.
Strength: The "tensile strength" is the maximum pulling force the bolt can handle before breaking. High tensile bolts have significantly higher tensile strength and yield strength (resistance to deformation) than standard fasteners.
Grading: High tensile bolts follow standardized grade classifications, with the higher number indicating greater strength. For metric bolts, the number is often marked on the bolt's head (e.g., 8.8, 10.9).

Durability: They are known for their strength and durability in demanding conditions and are available with various coatings, such as zinc plating or hot-dip galvanizing, to resist corrosion.

Identification: The grade marking is an essential feature for identifying high tensile bolts. For example, a metric grade 8.8 bolt has a minimum tensile strength of 800 MPa and a yield strength of 640 MPa.

Common high tensile bolt grades

Grade	Material	Nominal Tensile Strength	Application Examples
8.8	Medium carbon steel, quenched and tempered.	800 MPa	General industrial and machinery applications, construction.
10.9	Alloy steel, quenched and tempered.	1040 MPa	Automotive, heavy engineering, and structural steel.
12.9	Ultra-high strength alloy steel, quenched and tempered.	1220 MPa	High-performance and heavy-duty jobs, such as securing engines.

Applications

High tensile bolts are vital for securing critical joints where safety and structural integrity are crucial. They are used in numerous industries, including:

Construction: Steel structures and bridges.
Automotive: Engines and chassis.
Machinery: Heavy engineering and equipment.
Energy: Wind turbines and power plants.
