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.
Ordinary hexagon socket bolts are grade 4.8, whereas high-strength hexagon socket bolts are grade 8.8 or higher, including grades 10.9 and 12.9, which offer significantly greater tensile and connection strength.
They are available in stainless steel materials (such as SUS201, SUS304, SUS316, A2-70, A2-80, A4-80) and steel grades ranging from 4.8, 6.8, 8.8, to high-strength 10.9 and 12.9.
Because the nail head of the hexagon socket screw penetrates into the machinery, it provides extremely high connection strength, requiring a matching Allen key or hex socket wrench to properly access and torque the screw.
They are widely used in building industry machinery, machine tools, electronics, electrical appliances, chemical processing, water conservancy, furniture, automotive, aerospace, and marine industries.
Grade 12.9 hexagon bolts generally refer to high-strength, knurled, oil-colored black hex socket head screws, which are ideal for heavy-duty industrial applications.
