Stainless Steel Shoulder Bolts have an integral shoulder or journal below the head and above the thread. These are machine screws sometimes known as stripper bolts. They have a versatile usage and specific properties. The Shoulder Head Bolts are made from different material grades and in different sizes according to the different standard specifications.although there are different materials used for the making of these bolts and screws the 304 is the most used of all grades. the three 04 material has great advantage as it is less costly and has good strength and good corrosion resistant properties against general corrosive materials.
The 316 Stainless Steel Shoulder Bolts are used in the making of marine and sea water equipment and hardware. The material has chromium molybdenum and nickel in ample percentages that it makes it better use for chloride ion rich components. There are different types of materials such as austenitic stainless steel ferritic stainless steel duplex stainless steel and alloy steel materials.
The Alloy Steel Shoulder Boltsare made for the great strength and versatility to be used in many industrial applications such as oil and gas Petro chemicals Pharmaceuticals and in water supplies as well. Hex Head Shoulder Bolts can range in dimensions greatly. The length of the walls can range up to 24 inches and the diameter can range from 1/4 inches up to two inches. Stainless Steel Shoulder Bolts Supplier in India, can be used in different applications that have high vibrations and high temperature high pressure necessities.

Table of Content
A stainless steel shoulder bolt also referred to as a shoulder screw, is a machine screw with a smooth, cylindrical section between the threaded section and the head. Overlapping in use with bushings, the product made from corrosion-resistant stainless steel is used where rotational, sliding, or alignment functions are present in a piece of equipment or hardware, such as machinery or moving components. The smooth shoulder enables an easy pivoting or sliding of the parts in mechanical assemblies to improve on the durability of the parts by increasing their performance.
