Fastener: Everything You Need to Know

Views: 188 Author: Site Editor Publish Time: Origin: Site

A fastener is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components. Welding is an example of creating permanent joints. Steel fasteners are usually made of stainless steel, carbon steel, or alloy steel.

 

Other alternative methods of joining materials include: crimping, welding, soldering, brazing, taping, gluing, cement, or the use of other adhesives. Force may also be used, such as with magnets, vacuum (like suction cups), or even friction (like sticky pads). Some types of woodworking joints make use of separate internal reinforcements, such as dowels or biscuits, which in a sense can be considered fasteners within the scope of the joint system, although on their own they are not general purpose fasteners.

 

Applications

When selecting a fastener for industrial applications, it is important to consider a variety of factors. The threading, the applied load on the fastener, the stiffness of the fastener, and the number of fasteners needed should all be taken into account.

 

When choosing a fastener for a given application, it is important to know the specifics of that application to help select the proper material for the intended use. Factors that should be considered include:

· Accessibility

· Environment, including temperature, water exposure, and potentially corrosive elements

· Installation process

· Materials to be joined

· Reusability

· Weight restrictions

 

Types

A threaded fastener has internal or external screw threads. The most common types are the screw, nut and bolt, possibly involving washers. Other more specialized types of threaded fasteners include captive threaded fasteners, stud, threaded inserts, and threaded rods.
