Roll-fast is the biggest manufacturer of larger diameter high tensile bolts & nuts in India. There are many grades available, including M-16 to M-100 in 8.8, 10.9, and 12.9 grades. The High Tensile Bolts is a bolt with high tensile strength. The composition of a material can vary depending on its grade. these bolts have a higher yield strength and tensile strength than regular mild steel-grade bolts. Because of their high tensile strength, the majority of these are chromium nickel and nickel-copper alloys. Commonly used in engineering-type projects or heavy load applications where a high tensile hex bolt is required.
