在金屬結構製造過程中，螺絲是一個不可或缺的元件。螺絲的作用是將各個金屬部件連接在一起，即使只是一個小小的螺絲，它的重要性絕對不可小覷。螺絲的規格、尺寸、硬度、螺紋、孔徑等細節都需要精準計算和加工，才能確保金屬結構的穩固性和安全性。
除了螺絲，製造金屬結構時，墨水也是不可或缺的材料之一。墨水通常用於標記金屬材料的位置、尺寸，以便在製造過程中準確定位和加工。墨水的選擇和應用也需要具備一定的專業知識，以確保標記清晰易讀，並且不會對金屬材料產生影響。
金屬結構製造是一門結合工藝、設計、材料和技術的綜合性工程。螺絲和墨水雖然看似微不足道，卻扮演著不可或缺的角色，保證了整個製造過程的順利進行。

Title: The Key Elements in Metal Structure Manufacturing - Screws and Ink
Article: In the process of manufacturing metal structures, screws are an indispensable component. Screws are used to connect various metal components together. Even though they may seem small, screws play a vital role in ensuring the stability and safety of metal structures. The specifications, dimensions, hardness, threads, hole sizes, and other details of screws need to be precisely calculated and processed to guarantee the structural integrity and safety of metal structures.
In addition to screws, ink is also a crucial material in the manufacturing of metal structures. Ink is typically used to mark the positions and dimensions of metal materials, facilitating accurate positioning and processing during manufacturing. Proper selection and application of ink requires specialized knowledge to ensure clear and readable markings without affecting the metal materials.
Manufacturing metal structures is a comprehensive engineering discipline that combines craftsmanship, design, materials, and technology. Despite appearing insignificant, screws and ink play indispensable roles in ensuring the smooth progress of the manufacturing process.
