SS Bolt Grade Suppliers in india at low price according to ASTM A403/ ASME SA403 Standard
Viha Steel & Forging is one of the leading stainless steel bolts manufacturers in india and we produce the bolts in various stainless steel grades. The stainless steel bolts grade 304, 316 and 310 are most common in the 300 series. These are also mostly used in different applications for their strength, corrosion resistance and hardness. There are different types of bolts that are suitable for different application types.
The stainless steel coach bolts or carriage bolts are used to carry large loads. They are specified to connect loads to them. The load bearing applications in construction, transportation and other applications use these bolts. The stainless steel toggle bolts are made in different dimensions ranging from M03 to M60 in diameter. The length of the bolts ranges from 6mm to 500mm and the dimensions vary according to the different ASME and ASTM standards. There are different special types such as the stainless steel square u bolts.
The U bolts are used in applications where the U shape is necessary to connect two parts on the same side. The metric bolts are in use nowadays and the m8 stainless steel bolts are a medium size bolts that are used in different common applications. The prices of the bolts vary with the material grade, dimensions, shapes and types of the bolts. The ss bolt price is high for the high alloy bolts and is low for the low alloy 304 grade bolts. Please feel free to contact us for more information and the ss bolt torque chart.
