Non-standard customized cup head bolt.
A non-standard
customized cup head bolt is a bolt with unique specifications designed and manufactured according to specific customer requirements. Unlike standard bolts that follow national or industry standards in terms of head shape, thread specification, and length, non-standard cup head bolts can be customized in aspects such as head size (e.g., diameter and height of the cup head), thread length, thread precision, and material.
The cup head of the bolt provides a better bearing surface, enabling the bolt to distribute pressure more evenly when tightened. Customization may be required for special application scenarios, such as in precision instruments where high precision is needed, or in the aerospace field where extreme environments demand specific properties. It can also be for aesthetic design needs, for example, in high-end furniture or decorative equipment to match the surrounding environment.
The manufacturing process includes design stage where detailed specifications are determined, raw material preparation by selecting appropriate metal materials based on requirements, processing using numerical control equipment for shaping the cup head and thread, and quality inspection to ensure dimensional accuracy, mechanical properties, and surface quality.
Non-standard customized cup head bolts are widely used in fields such as machinery manufacturing for key connections in large equipment, in the automotive industry for engine components, and in the construction industry for decorative and functional connections in special building structures.
