标准范围

本文件规定了螺纹尺寸为ST2,2至ST9,5的钢制热处理自攻螺钉的机械和物理性能？1478，当在环境温度范围10？℃至35℃？℃，以及相关的试验方法。自攻螺钉设计用于在金属板上形成配合螺纹，而其自身螺纹不会变形。自攻螺钉在设计上不打算预紧，即使它们在安装后会经历不同程度的低水平拉伸应力。

This document specifies the mechanical and physical properties of heat treated tapping screws made of steel, with thread sizes ST2,2 to ST9,5 in accordance with ISO 1478, when tested at the ambient temperature range of 10 °C to 35 °C, and the related test methods.

Tapping screws are designed to form mating threads in sheet metals, without their own threads being deformed. Tapping screws are not intended to be pretensioned by design, even though they can experience varying degrees of low-level tensile stress after installation.
