Machine screw custom need to pay attention to?

In today’s Internet, it is easy and fast for us to buy what we need. However, when we buy, we sometimes look at the picture clearly good, but the actual quality of the goods is very poor. So we need to pay attention to the screening when buying. Especially when the machine screw custom, so it needs to pay attention to what?

First, when customizing the machine screw, we should tell the manufacturer that the thread should pass the check gauge of 6g or 6h. The main reason for this is to prevent manufacturers from cutting corners.

Two, the machine screw size to be measured. Since we usually mark the tolerance on the drawing when we place the order to the manufacturer, we need to measure the screw size when the manufacturer delivers it to ensure that this size is what we need.

Three, pay attention to the screw material and surface treatment. If we are buying, we can ask the manufacturer for material report, shipment report. And when we get the screws we have to look at the surface treatment of the screws.

In addition, we may also pay attention to their delivery time, price, etc. when customizing machine screw, and only after comprehensive comparison will we decide which screw manufacturer to buy.
