Flat washer part number 0301232100

The Atlas Copco flat washer part number 0301232100 is a genuine original auxiliary fastening component specifically designed for the GA series screw air compressors. It precisely fits various bolt and screw connection scenarios of GA models and is commonly used in conjunction with hex bolts, set screws, and other fasteners. As a key auxiliary element in the structural connections of GA models, this flat washer primarily serves three core functions: First, it increases the contact area between the bolt or screw and the connected part, distributing the fastening force evenly across the surface of the connected components to avoid deformation or damage caused by excessive local pressure, particularly protecting thin-walled parts such as the compressor housing and panels of GA models. Second, it fills minor surface irregularities of the connected parts, reducing fastening loosening due to uneven contact surfaces, enhancing the sealing and stability of the connection points, and preventing connection failures caused by operational vibrations. Third, it isolates the bolt head from the connected part, preventing wear from direct friction between metal components and avoiding adhesion due to bolt corrosion, thereby facilitating component disassembly and reassembly during subsequent equipment maintenance.
As a genuine original accessory, the production of this flat washer strictly adheres to Atlas Copco's high-standard quality system. It is manufactured from high-strength carbon steel or stainless steel through precision stamping processes, offering excellent flatness and wear resistance. It can withstand temperature variations and vibration environments during the long-term operation of GA models, preventing functional failures caused by material degradation. Its dimensional parameters, such as inner diameter, outer diameter, and thickness, fully match the specifications of the corresponding bolts and mounting holes of GA models. It can be accurately fitted onto the bolt shank, forming a perfect fit with the bolt and connected parts, allowing direct assembly without additional processing or adjustments, ensuring that the auxiliary fastening effect aligns with the original design standards. Through pre-delivery dimensional accuracy inspections, hardness tests, and anti-corrosion performance verifications, this flat washer provides reliable auxiliary fastening support for various connection points of GA series air compressors. It helps maintain the stability and durability of structural connections, reduces failures caused by connection issues, and ensures the long-term efficient operation of the entire machine.
