Fasteners
What is a Fastener?A fastener is a non-permanent or permanent mechanical tool that rigidly connects or affixes two surfaces or objects together. Non-permanent fasteners can easily be removed without damaging the joined materials. The removal of permanent fasteners might require substantial force and might damage the connected surfaces.

are designed to be a long lasting form of secure connection.
The wide range of fasteners includes screws, nails, nuts, bolts, and washers that come in different sizes, types, and configurations. Fasteners are one of the most used tools for building, fabricating, and configuring a variety of products and industrial equipment.

that range from the common nail to huge bolts to hold heavy duty manufacturing equipment in place. They can be generic or specially designed to fit an application. Every industry and manufacturer has a different and unique use for these valuable tools.
The variability between fasteners is due to the extreme forces that are placed on them. The purpose of fasteners is to hold parts, components, and pieces of machinery together in the presence of excessive vibrations and pressure while retaining the ability to disassemble the pieces when necessary.There are several ways to separate, classify, and categorize fasteners, which include permanent and non-permanent as well as threaded and non-threaded. In the permanent classification are rivets and couplings that cannot be removed. Screws and دیدن لینک ها برای شما امکان پذیر نیست. لطفا ثبت نام کنید یا وارد حساب خود شوید تا بتوانید لینک ها را ببینید.
fall into the threaded classification, while dowel pins and blind fasteners are non-threaded and permanent.

Bolts

and are used to hold two non-threaded pieces together. The head of a bolt, which comes in several varieties, is attached to the threaded male end. Bolts are classified by their shape and type of head.

Anchor BoltsAnchor bolts are referred to as "cast in place," which means they are included in the fabrication of the component or part and are permanently attached to it.

are designed for specific jobs. They are an industrial bolt that has been embedded into concrete for securing columns and supports to foundations.

NutsA nut is a fastener with an external thread that is used with a mating bolt that is of the same size. There are several varieties of دیدن لینک ها برای شما امکان پذیر نیست. لطفا ثبت نام کنید یا وارد حساب خود شوید تا بتوانید لینک ها را ببینید.
that include box and hex types as well as several other specialty kinds, configurations, and designs.

have notches on one end that allow for the insertion of a pin.

Types of WashersWashers are small, circular, metal disc in the shape of an annulus, halo, donut, or ring that is used to distribute the force of a screw, bolt, or nut. They can relieve friction, stop leakages, maintain tension, prevent corrosion, and serve as a spacer or separator. The wide and varied uses of washers has made them a necessity in a number of applications.The many varieties of دیدن لینک ها برای شما امکان پذیر نیست. لطفا ثبت نام کنید یا وارد حساب خود شوید تا بتوانید لینک ها را ببینید.
are further enhanced by the many types of materials used to produce them, which include zinc, copper, brass, iron, carbon steel, and stainless steel. Certain applications require specialty washers that are made from non-metallic materials such as plastic, rubber, ceramics, and phenolic.
The types of washers can be divided into three categories, which are plain, spring, and lock. In each of the categories are specialized forms that are designed to serve a specific or unusual function.The many functions of washers include:
  1. Reduction of friction

Distribution of pressure

Blockage, cessation, or elimination of leakage
[*]
Separation of components
[*]
Enhancement and securing of connections from vibrations and shock

The group of permanent fasteners do not have threads and can be quickly installed without the need of extra fastening components.

Washers relieve friction, stop leakages, maintain tension, prevent corrosion, and serve as a spacer or separator.
[*]
The three methods used to produce fasteners are machining, cold forging, and hot forging; these are commonly used methods for forming and producing metal parts.
