HEX Head Cap Screws are actually called in many ways, for example, they can be called external hexagonal bolts, external hexagonal screws, and hexagonal bolts. It all means the same thing. It's just that the personal name is different. Ordinary bolts are divided into three types: A, B, and C. The first two are refined screws, which are rarely used. Generally speaking, ordinary screws refer to C-level ordinary screws. So do you know what its uses are? Let’s follow the Special Headed Bolt YZP editor to have a brief look at it!
The outer HEX Head Cap Screw is a matching nut, which is used as a component to fasten and connect two connected parts with through holes. It is a more commonly used bolt. There are A-level and B-level external hexagons that are used more and more important. And it is more used in occasions where assembly accuracy is high, and when subjected to greater impact, vibration or alternating load. The HEX Head Cap Screw outside Class C is used where the surface is rough and the assembly accuracy is not high.
The threads on the outer HEX Head Cap Screw are generally fine-threaded ordinary threads, and the spiral-threaded ordinary threaded outer hexagonal screws have good self-pinning properties. They are mainly used for thin-walled parts or occasions subject to impact, vibration or alternating loads. Generally, they are made into partial threads. Full-threaded hexagonal screws are mainly used for the outer hexagonal diameter with short nominal length and the occasions that require longer threads. Hexagonal screws with holes are used in situations where a hexagonal screw is required for locking. Hexagonal screws with reamed holes can accurately fix the relative position of the connected parts. And can be sheared and squeezed by the force of the die.
In summary, the editor of Special Headed Bolt YZP tells: Some knowledge about the use of HEX Head Cap Screw, I hope you can learn more through the above introduction.
