The inner hexagonal countersunk head is rounded with a concave hexagon in the middle, and the countersunk screw is the common hexagonal side of the screw head. Hexagon socket head screws are often used on machinery, mainly for easy fastening, disassembly, and not easy to slip.

The countersunk head tapping screw material is generally made of carbon steel, and the surface hardness of the material after heat treatment is not less than 45HRC. Compared with the threads of ordinary screws, the pitch is large and the small diameter is slightly smaller at the same large diameter. It has been standardized and is usually used on doors and windows and iron sheets.

The tail of the truss head self-drilling screw is drill-tailed or pointed-tailed, which does not require auxiliary processing. It can directly drill, tap and lock on the setting materials and foundation materials, which greatly saves construction time. Compared with ordinary screws, the self-drilling screws have higher toughness and maintaining force, and the long time after combination is not loose. The use, safe drilling and tapping are completed at one time, and the operation is simple.

Hexagon socket button head screws, also referred to as hexagon socket head bolts, cup head screws, and socket head screws, are not the same, but the meaning is the same. Commonly used Hexagon socket button head screws are also 4.8, 8.8, 10.9, 12.9. Also called the hexagon socket screw, also called the hexagon socket bolt. Its head is a hexagonal head and is also a cylindrical head. Divided into stainless steel and iron by material. Stainless steel is made of stainless steel SUS202 Hexagon socket button head screws. This is made of stainless steel. It is made of stainless steel SUS304 Hexagon socket button head screws and stainless steel SUS316 Hexagon socket button head screws.

The self-drilling screw of the horn is a kind of threaded fastener which is self-drilled in the pre-drilled metal or non-metal material. The self-drilling screw of the horn does not require a nut with a female thread, and the female thread is drilled on the material while being screwed in.
