The Atlas Copco hex bolt part number 0147125203 is a genuine original structural fastening component specifically designed for the GA series screw air compressors. It precisely meets the connection requirements of key areas such as the main unit housing, cooling system components, and electrical control cabinet of GA models. As a core element for structural assembly and component fixation in GA models, this hex bolt primarily serves three critical functions: First, it tightly connects components like the compressor main unit cover and bearing end covers through axial preload force, resisting vibration impacts during equipment operation and preventing structural noise or displacement caused by loosening parts. Second, in scenarios such as pipeline bracket and sensor fixation, it provides stable support for auxiliary components, ensuring all parts maintain their preset installation positions during operation and guaranteeing system coordination. Third, when used with washers, nuts, and other accessories, it forms a reliable fastening structure, enhancing the anti-loosening performance of connection points and avoiding bolt loosening due to vibration after long-term operation.
As an original genuine part, the production of this hex bolt strictly adheres to Atlas Copco's high-standard quality system. Made from high-strength alloy steel through tempering treatment and precision thread processing, it offers excellent tensile strength and fatigue resistance, capable of withstanding temperature variations and load fluctuations during long-term operation of GA models, preventing deformation or fracture. Parameters such as hex head size, thread pitch, and shank diameter are highly consistent with the design specifications of GA models, achieving original assembly standards when matched with corresponding installation holes and nuts. It allows smooth assembly without additional grinding or adjustments, ensuring uniform stress distribution at each connection point. Through pre-delivery hardness testing, corrosion resistance evaluation, and torque verification by the manufacturer, this hex bolt provides durable and reliable structural fastening for the GA series air compressors, helping maintain overall structural stability, extend the service life of core components, and ensure long-term efficient operation of the entire machine.
