Grade 8.8/10.9 High strength DIN 912 Hexagon Socket Head Cap Screw
Grade12.9 DIN 912 SCREW
Hexagon socket head screws and countersunk head screws are very similar. When the nail head penetrates into the machine, its connection strength is very high, so the corresponding hexagon socket wrench must be used during Install and remove screws. Generally, it is widely used on various machine tools and its accessories.
Hexagon bolts are classified into ordinary and high strength according to their strength. Ordinary hexagon socket bolts are grade 4.8, high strength hexagon socket bolts are grade 8.8 or higher, including grades 10.9 and 12.9. Hexagon bolts of grade 12.9 generally refer to knurled, oil-colored black hex socket head screws.
Hexagon screws are widely used, ranging from small hardware to small electronics and electrical products. Mechanical equipment products, from cars, ships, aircraft cannons. In short, hex screws are mainly used in the fields of electronics, electrical appliances, electrical, electricity, chemicals, water conservancy, machinery and equipment, furniture, and other fields.
These screws comply with various international standards including DIN 912, GB, ISO, JIS, BA, and ANSI, ensuring global compatibility and reliable performance.
We offer a wide range of grades including stainless steel SUS201, SUS304, SUS316 (A2-70, A2-80, A4-80), as well as carbon steel grades 4.8, 6.8, 8.8, 10.9, and high-tensile 12.9.
Ordinary hexagon socket bolts typically fall under grade 4.8. High-strength hexagon socket bolts are rated at grade 8.8 or higher (including 10.9 and 12.9), offering superior connection strength for heavy-duty applications.
They are widely applied in the building industry, machinery, electronics, electrical appliances, chemical equipment, water conservancy, automotive manufacturing, and furniture production.
Due to their high connection strength and recessed socket head design, a corresponding hexagon socket wrench (Allen key) must be used for secure installation and removal.
