Professional production of customized non-standard screws and understanding of precision screw classification

Non standard screws refer to those that are selected in specifications outside of national standards, use special sizes, and require special drawing and processing for their pitch and diameter. The tools used also require special grinding, and are commonly used in applications with fewer parts. Shenzhen Shendingsheng Hardware Products Co., Ltd. is the preferred non-standard screw manufacturer, specializing in the production, processing, and customization of various non-standard screws, precision screws, special screws, and other non-standard screw related products.
　　
Precision screws are classified into self tapping precision screws and machine screw precision screws. Self tapping precision screws are mainly characterized by a pointed tail and self tapping teeth. It's hard to say about thread threads, there are self tapping thread threads and organic thread threads. There are many shapes of self tapping precision screw heads, including pan head, countersunk head, semi countersunk head, and head shapes with and without pads. The tail is characterized by pointed tail self attack, slotted self attack, B-tooth self attack, and fast tooth self attack.
Self tapping precision screws include pan head self tapping screws, countersunk self tapping screws, semi countersunk self tapping screws, self tapping screws with built-in pads, and tail cutting self tapping screws.
 
Machine thread precision screws refer to flat end screws with no pointed end at the tail, and their thread patterns are relatively uniform, similar in shape to self tapping screws in all aspects.
