A headless screw, as the name implies, is a screw without a head shape. It is mainly used to tighten the connection of the hole position in the connection mechanism where the countersunk head remains unchanged, and plays the role of locking, simple positioning and limiting.
It is a deformed product of the ordinary hexagon socket screw, also known as a machine screw or a top screw. Ordinary smaller machine screws are used for leather products.
One end of the headless screw is hexagonal, and the other end has several standards. For example, DIN916, DIN915, DIN914, DIN913, etc. It should be installed and used with a hexagonal wrench of the same size. This screw can be screwed in as a whole, so that it looks flat and beautiful.
When using a headless screw, screw the screw into the internal threaded hole of the part to be fixed, and then press the end of the screw on the surface of the other part (or the corresponding pit on the surface), even if the relative position of the two parts is fixed. The use scenarios of the flat end, concave end, and cone end are different, and the corresponding uses are also different.
Headless screws are commonly used in various precision machinery, instruments and meters, electronic products, communication products, toy locks, luggage, etc. It is suitable for occasions requiring simple equipment and components and is easy to install. The double-structured sealing device can work in harsh environments.
