With the development of the times and the progress of science and technology, bolts are currently available in various fields of equipment. Of course, bolts are divided into standard bolts and non-standard bolts. Standard bolts generally have relatively sufficient stock standard parts, but non-standard bolts are generally not manufactured based on the drawings and samples provided, so purchasing non-standard bolts generally requires customized production at the bolt manufacturer.
When manufacturing and selling non-standard bolts, there is always a bolt specification and bolt model. With non-standard bolt specifications and non-standard bolt models, we can understand exactly what specifications and sizes of non-standard bolts customers need.
Both non-standard bolt specifications and non-standard bolt models are based on national standard specifications and models. Generally, such non-standard bolts are known as ordinary non-standard bolts, which are commonly available on the market. Some non-standard bolts are not made according to national standards, specifications, models, and dimensions, but are customized according to the standards required for product materials. There is no stock on the general market at all. This will require drawings and samples to customize non-standard bolts.
When customizing bolts, we need to explain to the bolt manufacturer that the threads must pass through a go/no go gauge such as 6g or 6h. The reason for this is to prevent the manufacturer from cutting corners.
The size of bolts should be measured well, because when we place an order with a customer, tolerances are usually indicated on the drawing. Therefore, the bolt manufacturer should measure the size of the bolts when delivering them to ensure that this size is within our tolerance range.
Pay attention to the material and surface treatment of bolts. Of course, if stainless steel non-standard bolts are used, they are usually directly cleaned and dried for shipment. There are also a small number of customers who require surface treatment, which depends on the actual situation. We can ask the manufacturer for a material report and a shipping report. After receiving the finished product, it is also necessary to confirm the surface treatment of the bolts.
In addition, when customizing bolts, we should also pay attention to the manufacturer’s delivery date and initial order quantity. Generally, after the initial order quantity, the price will be relatively affordable, but this is also determined based on the difficulty of the product.
