Technical Specifications & Product FAQ
What sets SS 304 J Bolt apart from U Bolt?
The primary difference between these two types of fastening hardware lies in their intended use; SS 304 J-Bolts are used to anchor structures onto concrete foundations, while U-bolts are used to support and secure pipes and round bars. As an SS anchor bolt maker located in India, we produce all of these in fraction units for large FM project sites.
How do I determine torque values for bolts made from 304 SS - Stainless Steel?
It is very important to follow the makers’ recommendations when working with bolts made from 304 SS to avoid stripping threads; you can utilize A2-70 comparison tables for exact tightening of these bolts and apply lubricant when tightening to prevent galling.
Do you supply marine-grade fasteners in Mumbai and Chennai?
Absolutely, we produce 316 stainless steel fasteners and 316 Grade SS carriage bolts that have exceptional resistance to corrosion from salt-water being located in the Mumbai & Chennai area.
Although we offer a full range of Heavy Bolts, we are also one of the premier self-tapping screw manufacturers in India plus have become known as the preferred self-tapping screw supplier for Ahmedabad. Our full line of products includes SS 316 machine screws as well as internal/external star washers, which are used frequently in electronics and where high vibration occurs in automotive applications.
