安装螺栓英文

说法比较多，仅供参考：一、有无螺母（本人及多数人观点）螺钉一般是直接上在某件工件上，螺栓一般和螺母配合，做连接与紧固。二、受力方式（某资料定义）1、工具在圆周旋动的是螺栓，2、工具在圆心旋动的是螺钉，3、不能使用工具旋动的是螺柱。三、look（英文的定义）螺栓(bolt)定义是：headed fasteners having external threads that meet an exacting, uniform bolt thread specification (such as M, MJ, UN, UNR, and UNJ) such that they can accept a nontapered nut（螺母）.螺钉（screw)的定义是:Screws are defined as headed, externally-threaded fasteners that do not meet the above definition of bolts.

螺钉与螺栓有明确的专业名词术语，有明确的区分，不应随意称谓。 螺钉与螺栓的归类有100多项国家标准，仅螺钉的标准就有92项，标准太多，不方便记忆，不一一列出，但有规律可循，可以这样简单区分： 凡是圆头和螺纹杆构成的紧固件称为螺钉。其须使用起子和六角工具来拧紧，如开槽圆柱头螺钉、开槽沉头螺钉、十字槽沉头螺钉、内六角圆柱头螺钉、内六角沉头螺钉等等；没有圆头的各种紧定螺钉；各种定位螺钉、不脱出螺钉、轴位螺钉；各种滚花螺钉（带滚花就不用工具拧紧）；还有木螺钉和自攻螺钉等等。 带六角头、方头和螺纹杆的紧固件称为螺栓。没有六角头但两头带螺纹中间为光杆的称为双头螺栓（双头螺柱）、浑身都是螺纹的称螺杆，此外还有沉头方颈螺栓、T形槽用螺栓、地脚螺栓、U形螺栓。螺栓的拧紧器具为扭矩扳手、开口尺寸不变的各种形状的固定扳手、开口尺寸可变的活动扳手，液压紧配螺栓则需要液压泵等附件。 简而言之：用起子和六角工具拧紧的紧固件是螺钉，用扳手拧紧的紧固件是螺栓。 注意：不能按公称直径大小和长短来区分。例如一根M48长300mm的圆柱头紧固件，GB/70.1-2008标准将其定义为内六角圆柱头螺钉，不是螺栓。

螺栓螺母麻烦采纳，谢谢!
