High Tensile Hex Bolts Manufacturer in India
Caliber Enterprise is a leading High Tensile Hex Bolts manufacturer providing powerful and robust fastening solutions in applications where power and strength are needed. The high tensile hex bolts are made of high grade alloy steel and heat treated to give them high tensile strength and hardness. This is due to their hexagonal design of head which can be easily assembled using common tools hence they are applicable in construction, heavy machinery, automotive and structural works. These Bolts are also wear and stress as well as corrosion resistant and this guarantees long service life in the harsh environments.
High Tensile Hex Bolts are very desirable in the B2B market because of their dependability and resistance to failure when exposed to extreme loads. Power generation, shipbuilding, oil and gas, and infrastructure development industries are the ones that obtain such bolts as an essential connection that cannot be undermined in terms of its safety and stability. They have a high level of accuracy in threading and uniform quality which minimises downtime and maximizes productivity thus making them a favourite fastening solution in large scale industrial applications.

Frequently Asked Questions
What is a high tensile bolt?
A high tensile bolt is a fastener made from alloy steel or medium carbon steel that has been heat treated to increase its strength. These bolts are built to withstand high stress and heavy loads without bending or failing. They are widely used in construction, industrial machinery, automotive systems and structural frameworks where dependable strength is required.
What is the HT bolt specification?
HT (High Tensile) bolts are manufactured according to standards such as ISO 898-1, DIN 933, ASTM A325 and IS 1367. Common strength grades include 8.8, 10.9 and 12.9, where the first number indicates tensile strength in MPa (e.g., 800 MPa for Grade 8.8) and the second represents yield strength ratio. These bolts often feature coarse or fine threads and are made with black oxide, zinc or hot dip galvanized coatings for added protection.
What bolt has the highest tensile strength?
Grade 12.9 bolts have the highest tensile strength among standard metric fasteners. They provide a minimum tensile strength of around 1,220 MPa and are typically made from alloy steel. These bolts are used in extremely demanding environments such as high performance automotive systems, industrial machinery and heavy structural assemblies where maximum strength and fatigue resistance are critical.
