Hex Head Bolt Material:
The material of the bolt has an important impact on its performance and service life. According to different usage environments and requirements, appropriate materials should be selected. For example, stainless steel bolts are suitable for corrosive environments such as marine and chemical industries, while ordinary carbon steel bolts are suitable for general structural connections.

Hexagon Head Bolts Dimensions:
The size of the bolt, including diameter, length, etc., should be selected according to the thickness of the connection and the required preload force. Generally speaking, the length of the bolt should meet the requirements of the thickness of the connecting piece, and the installation space and adjustment allowance should also be considered. The diameter of the bolt should be selected according to the size of the pretightening force. If it is too large, it will lead to waste, and if it is too small, it may not meet the requirements.
