Frequently asked questions about this product (FAQ)
1. What is the purpose of through-hole bolts?
The use of through hole bolts is to empty the air in the space below the workpiece with threaded holes.
To ensure the vacuum environment of the vacuum equipment
2. What devices and equipment are through-hole bolts mainly used on?
Through hole bolts are mainly used in vacuum devices, vacuum containers, FPD manufacturing devices, semiconductor related equipment, electron microscopes, etc.
3. Is there a precision requirement for the inner hole of the through-hole screw?
Due to the main purpose of this hole being for ventilation, only the hole is guaranteed to be continuous without any requirements for positional tolerances such as concentricity and verticality.
The inner diameter can only guarantee general tolerances.
4. Are there any other materials available?
Due to its main use in vacuum environments, the material is currently mainly stainless steel SUS304. If there are other material requirements.
