Is The Stop Screw A Fastening Screw? How To Use Stop Payment Screws?

When it comes to stop payment screws, you may not be very familiar with them. In fact, it has multiple names. If named based on its shape and function, it is called a machine screw, a headless screw, or a set screw. Its English expression is set screw. It is a type of screw used to fix the relative position of mechanical components. According to the groove type, it can be classified into hexagonal socket set screws, hexagonal socket set screws, straight slot set screws, and square head set screws without grooves. The available materials include stainless steel, iron, brass, aluminum, titanium, etc.

Characteristics of stop payment screws
A stop screw with parallel first and second end faces, a threaded section between the first and second end faces, two parallel groove walls extending radially from the first end face to the second end face, and a groove bottom connecting the two groove walls, defining a radial groove through the groove wall and groove bottom; Its characteristic is that the adjacent parts of the groove wall and the threaded section have a side adjacent slope inclined from the threaded section towards the groove wall, and the groove bottom and the adjacent parts of the threaded section also have a bottom adjacent slope inclined towards the groove bottom.

The function and use of stop payment screws
The positioning pin of the stop payment screw plays the same role, usually used to connect two parts and fix them. Moreover, this type of screw can be screwed in as a whole, making it look flat and attractive. When using a stop screw, first screw the screw into the internal threaded hole of the part to be fixed, and then press the end of the screw tightly onto the surface of another part (or the corresponding groove on the surface), even if the relative position of these two parts is fixed. The usage scenarios of flat end, concave end, and conical end are different, and their corresponding purposes are also different. One slot, inner plum blossom, and inner hexagonal set screws are not suitable for situations where the screw is allowed to be exposed, while square head set screws without slots are suitable for situations where the screw head is allowed to be exposed.

The purpose of stop payment screws
Stop payment screws are commonly used in industries such as mining, metallurgy, textiles, various precision machinery, precision instruments, meters, electronic products, communication products, locks, toys, etc! Priority is given to situations where simple equipment and components are required, easy to install, with a dual structure sealing device that can work in harsh environments. Diverse structural forms, good universality and interchangeability.
Stop payment screws also need to be customized according to different application scenarios, and hardware stores usually cannot meet the requirements. One end of it is an inner hexagon, and the other end also has several standards. Such as DIN916, DIN915, DIN914, and DIN913. The specifications of the stop screw range from M1.6-M12, and the length ranges from 4MM-50MM. Specifically divided into hexagonal concave end set screws, hexagonal flat end set screws, hexagonal column end set screws, and hexagonal cone end set screws.
