Standard screws refer to standard screws such as national standards, ISO international standards, US standards, British systems, daily standards, moral standards, etc., rather than standard screws are based on standard screws. In terms of performance, the derivative of "upgraded" screws. Unlike the standard screws, the standard screws are relatively strong, but the non -standard screws are more targeted. Generally, the production of a non -standard screw is aimed at a certain model for a certain model. Product production, its performance is more fitted with product design.
Why are non -standard screws more expensive than ordinary standard parts screws?
On the one hand, because the non -standard screws are compared to test the production strength of the manufacturer, not to say that all manufacturers have the production capacity of this non -standard screw. On the other hand, it also has some special size and special strength requirements. Some even have requirements for its threads and screws, including its accuracy, strength, and its process process performance, and the price will naturally be more expensive.
You must understand its specifications before customization
Screw specifications, head size specifications, high specifications. If the size of the inner hexagonal screw is needed, the size of the angle is also needed, the diameter is different, the materials used are different, and the price will be different. Therefore, if we are preparing to buy non -standard screws, we need to strictly look at this part to buy more suitable products.
