Are the cheap stainless steel self tapping screws really good?

There are stainless steel self tapping screws everywhere on various platforms, and there are many screw prices and their low prices. Even below the cost price, are their products qualified?

Shi Shi Tong has bought three stainless steel self tapping screws at different prices and compared with the self-tapping screw produced by Shi Shi Tong. In which 2 suppliers quality is found to be unqualified, the first is that the material is not qualified, the low-quality stainless steel 201 is used instead of the stainless steel 304 with less nickel content, The second is that the threads do not have a stop gauge. The stainless steel self tapping screws produced in Shi Shi Tong is made of 316 material which is of type 304 or higher, and the shipment will be checked with the material and quality inspection.

The customer asked about the price of the countersunk stainless steel self tapping screws, said that the price of Shi Shi Tong is more expensive than the price on a certain purchase, but still hopes that Shi Shi Tong can help him produce, because the quality purchased online is unstable, the supply is also unstable, in fact, it also increases the internal procurement cost. Shi Shi Tong provided the stainless steel self tapping screw standard according to the customer’s requirements, the specification and size table of self-tapping screw. After the customer confirmed the size, the customer placed an order to produce it.
