How to produce long self tapping screws, and the cost is more cost-effective?

Long self tapping screws are much more expensive than ordinary screws because of the length relationship, the difficulty of production, and the type of machine being produced. So, how to make such a screw, the cost will be more cost-effective?

Many long self tapping screws involve a problem in production, that is, the mold. The cost of the mold is also more expensive than that of a normal screw because the mold is more complicated. Therefore, when asking about the price of long screw manufacturers, you can ask whether these screw manufacturers have made screws of similar specifications, and can you share a mold, so the cost of the mold will be saved.

In addition to the cost of the mold, the unit price of the screw is also important. The calculation of the unit price is related to the weight, material and surface treatment of the screw. When the material and surface treatment of the screw cannot be changed, we can see if the design of the long self tapping screws can be changed to reduce the weight of the screw. For example, change the big rod to a small one. A large rod means that the diameter of the portion of the head that is not threaded is as large as the thread. The small rod means that the portion of the rod that is not threaded under the head is smaller in diameter than the thread. If you change to a small pole, not only will the cost be reduced, but the cost of transportation will also decrease.
