T Head Bolt is a special fastener for photovoltaic projects, with many uses, including but not limited to the use of solar support, paper machine fixing, hydraulic power generation and wind power generation fan installation.
The design features of the bolt enable it to be automatically positioned and locked during installation and is usually used in conjunction with flange nuts for applications requiring high strength, light weight and easy maintenance.


The material of T Head Bolt is mostly stainless steel, such as 304 or 316 material, to ensure its corrosion resistance and durability in a variety of environments.
In addition, in order to prevent rust, you can take plating, passivation treatment, storage in a dry and ventilated environment and apply anti-rust oil and other measures to protect the bolt, thereby extending its service life and maintaining its good anti-rust performance.
