At the beginning of this year, Mr. Meng’s company used screws from another screw manufacturer. At the beginning of this year, Mr. Meng reached a cooperation with Shi Shi Tong screw manufacturers and supplied them with  m3 allen head screw . Mr. Meng found that the cost of this year was 15% lower than the cost of last year when they were sorting out the cost of the first half of the year.

The same is the  stainless steel  socket head cap screw , why the price is not the same? There are many reasons for the price difference: ★One is whether the dimensions are all the same. For example, one is M3*12  stainless steel socket head cap screw , and the other is M4*12 stainless steel hex socket screw. The size is different, the weight is different, and the price is different. ★Are the material grades used the same? For example, one is made of 201 stainless steel, and the other is made of 304HC stainless steel.
