About American standard hex socket stainless screws, is there any difference in price between half and full threads?

Mr. Song told the screw manufacturer of Shi Shi Tong that he needed to order several types of American standard hex socket stainless screws. The thread specifications are #4-40, but the lengths of the screws are 50mm, 60mm, 90mm, 105mm, and let us give him a quotation.

In the process of confirming with Mr. Song whether the American standard hex socket stainless screws are full teeth or not, Ms. Song explained that the price of full teeth and half teeth are different by the way. So how much is the price difference? This needs to look at several aspects:

One is the length of the full teeth. Does the manufacturer have the main mold or dental plate of this size? If not, then we need to add the mold cost of them.

Two, to see the size of half teeth. What is the length of the half teeth, and what is the diameter of the rod? If the diameter of the rod is about the same size as the diameter of the thread, it is generally necessary to open a mold, which also needs to see whether the manufacturer has the corresponding mold. If the rod diameter is similar to the grinding diameter of the thread, then it is generally not necessary to open mold.

Three, how much is the difference in weight? Generally speaking, when a manufacturer is in business accounting screws’ price, the cost of wire is occupied a lot, and the cost of wire can involve the weight of the wire.

 After listening to Ms. Song’s explanation, Mr. Song said that he would like to confirm the half teeth size of American standard hex socket stainless screwsand then find Ms. Song for a quotation.
