2、螺钉指螺丝（外文名：Screw）：利用物体的斜面圆形旋转和摩擦力的物理学和数学原理，循序渐进地紧固器物机件的工具。 螺丝是紧固件的通用说法，日常口头语。

螺栓在英文里叫做bolt，bolt翻译成中文是栓、闩、插销、门闩、门栓的意思，而螺钉在英文里叫做screw，screw翻译成中文是螺旋、拧、螺旋桨的意思，两者的区别就是螺栓是插入而螺钉是需要拧的，因此利用英文单词来区分螺栓螺钉比较直观。

2024年12月10日 · Bolts hold objects together with a nut, but screws work on their own. When you insert a bolt through an object, you screw a nut onto the threaded end to apply pressure and secure it in place. When you use a screw, the tension on its threads pulls the objects closer to hold them together securely.

Bolts and screws are sometimes distinguished by their use. According to these definitions, a bolt goes through unthreaded holes in parts and is secured by a nut, while a bolt mates with a threaded hole in one of the parts to be fastened.

2024年5月20日 · Screws and bolts may look alike, but they have different features and functions. Here's the lowdown on these essential fasteners.

Screw（ 螺钉 ）：是一种利用物体的斜面圆形旋转和摩擦力的物理学和数学原理，循序渐进地紧固器物机件的工具。 通常是由一个圆头和螺纹杆构成的紧固件， 不需要配合 螺母 使用 。

Bolt and screw are mechanical fasteners used to position and hold two or more components together. But they have unique applications and characteristics. Bolts are used with nuts, whereas screws make threads of their own or are used on the threaded component. But in some scenarios bolts can work as screws if used on the threaded component.

2024年11月27日 · While bolts and screws might seem similar at first glance, their differences in threading, installation, and application are significant. Understanding these distinctions can save time, improve safety, and ensure the durability of your project.

When To Use A Screw Versus A Bolt. Choosing between screws and bolts depends on the specific requirements of your project. Understanding when each fastener performs best can prevent misapplications and ensure structural integrity. Common Scenarios For Screws. Screws work best for lightweight or non-structural tasks.

2023年9月27日 · While both bolts and screws share the fundamental purpose of fastening objects, bolts rely on a separate nut for their operation and excel in scenarios that require adjustability and disassembly. In contrast, screws establish their threads within the material they penetrate and provide a secure and self-contained fastening solution.
