What Factors Affect The Size Of The Cross Screws?
When the cross screws does not know which type of screw head is, the size of the head cannot be specified. Before, when I first entered the fastener industry, I always thought that no matter what kind of head size the customer gave, someone could make it. The deeper you understand, the more you know that this is not the case. The head of the cross screws should not only take into account the maximum forming range of the material, but also the tolerances and process problems.
Shenzhen Shi Shi Tong screw manufacturer has been in the fastener industry for 20 years. A variety of non-standard, profiled screws have been produced. For example, the customer wants the M5’s pan head cross screws. Generally, the head size of the head-type Phillips head screw according to GB/T 818-2000 is: head diameter 9.14mm-9.5mm, head thickness is 3.52mm-3.7mm. But the customer said that he does not want standard Size, the head thickness is 3.1mm, the head diameter is 12mm, ask if we can do it.
This kind of screw is not a standard. In the case of the material given by the customer, it can be seen whether it can be produced. However, it is not easy to make a pan head of this size. The size of this cross screws head is the size of the truss head. It is recommended that customers can use large flat heads, and if they can, this kind of production will generally be very fast.
