1. What are MS, SS & GI Nut Bolt Fasteners?
MS, SS & GI Nut Bolt Fasteners are industrial fastening components made from Mild Steel, Stainless Steel, and Galvanized Iron respectively. They consist of a threaded bolt and a matching nut used to securely fasten two or more components together in construction, industrial, and engineering applications.
2. What is the difference between MS, SS and GI nut bolts?
MS (Mild Steel) nut bolts are economical and suitable for indoor applications. SS (Stainless Steel) offers excellent corrosion resistance and is ideal for marine and outdoor use. GI (Galvanized Iron) provides zinc-coated protection against rust, making it suitable for outdoor structural applications.
3. What are the tensile strength ratings for these fasteners?
MS nut bolts offer 300-440 MPa tensile strength, SS provides 500+ MPa, and GI delivers 400-500 MPa. High tensile grades like 8.8, 10.9, and 12.9 are also available for critical applications.
4. What grades of stainless steel are available for nut bolts?
We offer SS nut bolts in grades SS 202, 304, 304L, 316, and 316L. SS 304 is the most common general-purpose grade, while SS 316 offers superior corrosion resistance for marine and chemical applications.
5. What is Hot Dip Galvanized (HDG) coating?
Hot Dip Galvanized (HDG) coating is a process where GI nut bolts are dipped in molten zinc to create a protective layer against corrosion. This provides long-lasting protection for outdoor and structural applications.
6. What size range is available for nut bolts?
Nut bolts are available in sizes ranging from M6 to M64 (metric) and ¼" to 2½" (imperial). Custom sizes can be manufactured upon request for specific applications.
7. What is the difference between full thread and half thread bolts?
Full thread bolts have threads along the entire shaft length, providing maximum grip. Half thread bolts have a partially unthreaded shank, offering better shear strength and alignment for structural applications.
8. What head shapes are available for nut bolts?
Nut bolts are available in various head shapes including hexagonal (most common), square, socket, countersunk, and flange heads. Hexagonal heads allow for easy tightening using standard wrenches or spanners.
