The inner hexagonal groove cylindrical head Allen screw, known by various names like cup head screw or sleeve head cap screw, essentially refers to the same product. These screws come in different strengths: 4.8, 8.8, 10.9, and 12.9, and are also referred to as SHCS. They feature a hexagonal head, resembling a cylinder head, and are commonly made from stainless steel.
Among stainless steel variants, there are SUS202, SUS304, and SUS316 hexagonal sleeve head cap screws. SUS202 is a typical stainless steel material, while SUS304 and SUS316 offer higher corrosion resistance, especially in harsh environments like saltwater or chlorine-rich surroundings. However, SUS316 tends to be pricier due to its superior corrosion resistance.
The strength of hexagonal socket screws is evaluated based on grades such as 4.8, 8.8, 10.9, and 12.9. Hexagonal socket head nut screws, categorized as high-strength bolts in grades 8.8 to 12.9, are referred to as such.
Stainless steel 304, 316, and 316L, also known as 18-8 stainless steel, are common choices for general hardware applications. Stainless steel 316 stands out for its excellent corrosion resistance, particularly in saltwater and chlorine-heavy environments, albeit at a higher cost compared to 18-8 stainless steel.
Galvanized alloy steel and black oxide-treated alloy steel are other high-strength heat-treated alloy options. Galvanized steel offers moderate corrosion resistance, while black oxide polishing enhances the strength of alloy steel.
The ASME standard governs the diameter of sleeve cap screws, ranging from 0 to 2. These socket nut bolts adhere to the latest ASME B18.3 or IFI standards or can be customized based on customer specifications, offering options for full or partial threads. These socket nut screws are available in various materials and sizes.
