What’s wrong with a large head screw head that’s too big? Can it be done? large head screw factory

Recently, Shi Shi Tong large head screw factory has often received inquiries from some customers. The head size of the large head screw is larger than the standard one. What problems will there be in such a designed head size? At the same time, customers will also worry about whether we can produce?

Whether the large head screw can be produced depends on the multiple of the thread diameter, whether it is 2 times, 3 times, 5 times, or 5 times. Generally, it cannot be done if it exceeds 5 times. Also depends on the shape of the head.

The larger the head multiple, the higher the difficulty of molding, the more expensive the mold cost, and the higher the production cost. At the same time, when designing the larger head, a certain R angle must be left under the head to prevent the head from breaking easily when twisting.

Most of the large head screw have a large head, which is basically a ultra low head. This type of head is easier to shape. For example, the M4 ultra low head screw has a head diameter of 20mm. This Shi Shi Tong large head screw factory has produced it.

However, it is impossible to change to other head shapes, such as truss head, mainly because the mold of truss head is larger than that of ultra low head, and our existing machine cannot hold the mold of truss head; and if the customer requires the truss head to be no slotted or slotted, then you can print out the ultra low head first, and then go to the car. However, this production method will lead to a much higher cost of large head screw.
