Non-standard stainless steel screws are different from standard parts on the market, so when customizing non-standard stainless steel screws, how do we choose the type according to the head of the screw?
Non-standard stainless steel screws
1. Countersunk head
This type of head should be considered to be used a lot, because after it is screwed into the product, it will not protrude from the surface of the product and affect the appearance of the product, which is mostly used for the exterior of the product.
2. Semi-sunk head
Some heads have square necks or tenons under their heads to prevent them from turning when screw nuts are turned. There is a word groove on the head, and the diameter of the cross groove is relatively small. Generally, the diameter d is mostly below M10.

3. Pan head
The head of the pan head screw can have a slot, a cross slot, a plum blossom slot, etc., mainly for the convenience of using tools to screw, and it is mostly used in products with low strength and low torque, and is generally used in household appliances and other small-sized products. host products.
4. Hexagon head
The hexagonal head is also a common head shape in screw fasteners. Some hexagonal head fasteners also have tables, holes, bosses, and flanges. Hex head screws have high mechanical properties and are convenient for wrench tightening. Larger tightening torque can also be applied, and it is widely used. Hexagon head screws with bosses on the supporting surface or flange surfaces also have the function of washers. Enlarging the pressure bearing surface has a better anti-loosening effect. It can also be used for the connection of steel structures and important host structures.

5. Half round head
Generally, slotted round head screws are mostly used in occasions with small space and little force, while oblate head screws are mostly used for connection and fixing of thin-walled parts and plate structures.
6. Big flat head
The function of the square neck and the tenon is to fix the screw, and the tightening screw device is to fasten the connection of the metal parts.

7. Square head screws
The lag screw has a large head area, which is convenient for the wrench to tighten and turn. Larger tightening torque can be applied, and it is not easy to be unscrewed. Most of them are used for relatively thick structures that are often disassembled, but they are not suitable for parts that often need to be disassembled and moved.
8. Inner hexagonal head, flower-shaped head
Its function is the same as that of the countersunk head in use, but the strength and tightening torque are larger than that of the countersunk head.
