8.8 Graded Nut & Bolt

    Now a day, the growing concern for the safer building has increased immensely the requirement for the good quality of nut-bolts. For structural member, 8.8 graded nut & bolt are highly recommended. However, availability of consistent quality of nut bolt is not available in market. And the price of branded 8.8 graded nut & bolts is too high. In this context, after three years of continuous research, CSSL has developed nut & bolts which conforms to ASTM F568 High- Tensile Class 8.8 Bolts. Basically, the price of the developed nut & bolt is very much reasonable. The nut & bolts can be manufactured as per customer requirements.
