An Allen bolt, also known as a 316 SS Socket Head Cap Screw, is a type of fastener with a cylinder head and a hexagonal drive hole. Depending on the product's intended usage, these stainless steel socket head cap screws are made from a variety of stainless steel grades. One of the two most popular austenitic grades of stainless steel, for instance, is the 316 stainless steel socket head screw, which offers excellent mechanical properties like increased strength, hardness, and improved corrosion resistance.
Hex Socket Round Heads, also known as Stainless Steel Socket Button Screws, often have a dome-shaped head with an Allen key or a hexagon socket drive. In addition to being utilised in the construction of machinery, stainless steel socket shoulder screws are also used in the marine industry. In addition to serving as bearing pins and limiting the die springs in the stamp housing or the mold, they are found in pulley shafts and punch or die works.
When a screw is needed to hold or fasten two objects, Stainless Steel Countersunk Socket Screws are used, with the head of the screw being as close to the surface of the object as possible, which could then be covered by a piece of wood or a screw cap. One of the top producers of SS socket head cap screws is us.
