紧固件 锥形槽销 半长渐进式槽

[中文适用范围]： 本文件规定了钢和不锈钢锥形 groove 销钉的特性，这些销钉具有半长度渐进式凹槽（在插入端闭合）， nominal 直径为 1 mm 至 25 mm。这些带有凹槽的销钉旨在实现以下主要功能：定位或导向、装配部件的相对旋转，并且由于其形状易于安装以及由于弹性配合行为而具有中等程度的拔出阻力。有关带沟槽销钉的基本要求（包括功能原理和装配），请参见 ISO13669。 [外文原描述]： This document specifies the characteristics of taper grooved pins with half-length progressive grooves (with close-end at the insertion side), in steel and stainless steel, and with nominal diameter 1 mm to 25 mm. These grooved pins are designed to fulfil the main following functions: — positioning or guiding, and — relative rotation of the assembled parts, with an easy installation (due to its shape) and a medium level of pull-out resistance (due to the elastic fit behaviour of the pin). The general requirements (including functional principles for grooved pins and assembly) are specified in ISO 13669.
