The length of the extra long machine screws is the same, why is the price different?

Price is a sensitive topic, especially for people who buy. The same is true for people who purchase extra long machine screws. Why are the screws of the same specifications not the same price, some high and low, what is this related to?

Quantity. Basically, people who buy know that if the quantity purchased is different, the price is different. For example, one of the extra long machine screws of the same specification purchases 1000 pcs, and the other one purchases 10000 pcs. Their unit price is very different, and we also know that the quantity is large and the price is excellent.

Material. Screws can be made of many materials, such as 304 stainless steel, 316 stainless steel, copper, aluminum, carbon steel and so on. Different materials, their cost is not the same. For example, the cost of 304 stainless steel plus the cost of cleaning is basically 30 yuan a kilogram, while the cost of one kilogram of carbon steel is 8 dollars, which is nearly 4 times the price.

The cost of processing. Even with the same specifications, materials, and the number of extra long machine screws, but in different screw manufacturers, their processing costs are also different, because manufacturers in different places rent, wages, etc. are different, and this also caused processing The cost difference.
