Internal hexagonal cylindrical head bolt, also known as internal hexagonal bolt, cup head screw, or internal hexagonal screw, has different names but represents the same meaning. The commonly used hexagon socket head screws also have grades 4.8, 8.8, 10.9, and 12.9. Also known as internal hexagonal screw, also known as internal hexagonal bolt. Its head is hexagonal and also cylindrical. According to material, there are stainless steel and iron. There are stainless steel SUS202 internal hexagonal cylinder head screws, which are made of ordinary stainless steel material. There are stainless steel SUS304 internal hexagonal cylinder head screws and stainless steel SUS316 internal hexagonal cylinder head screws. Iron is classified according to the strength grade of hexagon socket head screws, including grade 4.8 hexagon socket head screws, grade 8.8 hexagon socket head screws, grade 10.9 hexagon socket head screws, and grade 12.9 hexagon socket head screws. Grade 8.8-12.9 hexagon socket head cap screws are called high-strength and high-grade hexagon socket bolts.
Process
1. Drill holes according to the diameter of the inner hexagon to meet the requirements.
2. Use a cold heading machine to upset the inner hexagon.
3. A single piece can be punched with a hexagonal punch and punched out with a hammer.
purpose
Similar to countersunk screws, the nail head is embedded in the machine and has a higher connection strength, but the screw must be installed and removed using a corresponding hex wrench. Generally used on various machine tools and their accessories.
