Grade 8.8 Bolts

High Tensile Grade 8.8 Hex Bolt and Class 8.8 Studs manufacturer in India.

The High Tensile Grade 8.8 is known as the structural grade for manufacturing bolts. They have high tensile strength and possess good ductility. We are a renowned manufacturer of High Tensile Grade 8.8 Hex Bolts, where clients can get different types of fasteners with their preferred coatings. The grade 8.8 can also be defined as the medium carbon steel specification for bolts. AS1252 Structural Bolts are usually heat treated by methods like quenching and tempering. Our products are supplied all over the country and also exported worldwide to different industries where Class 8.8 Studs has varied applications. The grade 8.8 bolts can work perfectly, even in extreme environments, which is a big positive side. In addition, we offer customization in terms of dimensions and finishes for our High Tensile Grade 8.8 Fasteners.

As mentioned earlier, the HT Class 8.8 Nuts we manufacture have a wide range of applications. They are used in different railroad, processing, and motor equipment. We have an experienced team who supervise the production process with expertise in the field and help in delivering the best products every time. We use the latest machinery in the manufacturing process of BS 3692 Grade 8.8 Hex Bolts to get dimensionally accurate products. This saves our time and helps us to always adhere to the delivery timelines. We also have a huge warehouse, where there is a considerable M20 Grade 8.8 Galvanised Bolts stock. Therefore, depending on our client’s requirements and product availability, we can offer fast doorstep deliveries.

We maintain all the industrial and international standards while manufacturing ASME SA324 8.8 Stainless Steel Bolts. Our products go through several quality checks and pass them to get certified. We also focus on packaging our products and use good quality wooden boxes to avoid any transportation damages.
