304 Hexagon Socket Countersunk Head Bolts M8

DIN7991 hexagon socket countersunk head screws are made of carbon steel and stainless steel. The performance grades of carbon steel hexagon socket countersunk head screws are 8.8, 10.9 and 12.9. The standard can refer to GB3098.1. Carbon steel materials generally require surface treatment, such as oxidation and electroplating. If other surface coating or surface treatment is required, it can also be negotiated. The commonly used stainless steel hexagon socket countersunk head screws on the market are mostly SUS304 and SUS316, and the stainless steel material has strong corrosion resistance and heat resistance. SUS304 has medium work hardening rate, which is suitable for general cold working and drawing; SUS316 has stronger corrosion resistance than 304. It is especially suitable for marine and chemical media, with better corrosion resistance and pitting resistance. Our factory mainly produces SUS304 DIN7991.Like Hex Bolt, our factory's countersunk head bolt is also highly praised by customers.
