M3 A4 80 316L Stainless steel 304 Cap Head Hex Socket Machine Screws
Description:
Inner hexagonal groove cylindrical head Allen screw, also known as cup head screw, sleeve head cap screw, its name is different, but the product is the same. Strength of all kinds of machines is 4.8, 8.8, 10.9 and 12.9. Also known as SHCS. Its head is a hexagonal head, and so is the cylinder head. The material is stainless steel. There are SUS202 stainless steel hexagonal sleeve head cap screw, which is common stainless steel material, SUS304 stainless steel hexagonal sleeve head cap screw, SUS316 stainless steel hexagonal sleeve head cap screw. The iron was evaluated by the strength of hexagonal socket screw. There were 4.8 internal hexagonal socket screw, 8.8 internal hexagonal socket screw, 10.9 internal hexagonal socket screw and 12.9 internal hexagonal socket screw. Hexagonal socket head nut screw is called high-strength high-grade hexagonal bolt in grade 8.8-12.9. Standard number: GB/T 70.1-2008.
Stainless steel 304, 316 and 316L, also known as stainless steel 18-8, are the most common stainless steel for general hardware applications. Stainless steel 316 is a stainless steel with high corrosion resistance. Ideal salt water and chlorine environment. It's more expensive than 18-8. Galvanized alloy steel is another kind of high strength heat treatment alloy steel. Moderate corrosion resistance galvanizing. Black oxide polishing agent for alloy steel is also a very high strength heat treatment alloy steel. Black oil finishing.
ASME standard sleeve cap screw diameter is 0-2. These socket nut bolts are manufactured according to the latest ASME B18.3, IFI or customer specified standards, with full or partial thread options. We stock these socket nut screws in our various materials and sizes.
