自攻螺钉是当前世界上流行的轻结构新型紧固件。介绍了自攻螺钉的特点及其对钢材性能的特殊要求，分析了影响该品种钢质的主要因素及开发的相应对策。主要是控制成品的硅≤０．１０％，酸溶铝≥０．０２％，钢中氮≤６０×１０－６。另外还应设法降低非金属夹杂物含量，减少偏析与不致密性，提高表面质量与线材尺寸精度等，在开发新产品的各种对策中，新工艺、新技术、新装备三者相互关联，是不可分割的一个整体。
Self-tapping screws are the new light-weight fasteners in the world. The characteristics of self - tapping screws and their special requirements on the properties of steel are introduced. The main factors that affect the quality of the steel and the corresponding countermeasures are analyzed. The main control of finished silicon ≤ 0.10%, acid-soluble aluminum ≥ 0.02%, steel nitrogen ≤ 60 × 10-6. In addition, we should also try to reduce the content of non-metallic inclusions, reduce the segregation and non-compactness, and improve the surface quality and wire size accuracy. Among the various measures for developing new products, new technologies, new technologies and new equipment are all interrelated, It is an indivisible whole.
