High Tensile Fasteners manufacturer in India

Reliable HT Nut Bolt manufacturer in India

What is High Tensile Fasteners?

High tensile fasteners are made of high strength materials such as medium carbon steel or alloy steel and they heat treated to enhance their strength and mechanical properties. They are specifically designed to withstand high stree, load and tension without failing. High strength nuts and bolts are manufactured as per ISO 898-1 or BS EN 14399 standard.
