Classification of Fasteners
Fasteners can be found, used, and applied in a variety of fields, ranging from industrial to manufacturing to the military and in business. Fasteners literally make up and contribute to the foundation that holds many of the buildings and mechanisms that we use every day. And while fasteners are very common, there are many distinct variations, the differences of which are important to understand (particularly for those working in aviation manufacturing and in the supply chain sectors). To put it simple, a fastener refers to a type of mechanical component used to fasten or tighten two or multiple pieces so as to form one cohesive piece. Fasteners can be applied on many different items including machinery, equipment, vehicles, ships, railways, bridges, etc. The different types of fasteners are categorized by performance, specifications, serialization, etc. In this guide, we will explore a few basic types of fasteners.
Stud: The stud
is a type of latch containing no head and with only threads placed on the end. In order to connect a stud, one end of the item must be attached to the side with the internally threaded opening. This attachment will result in a detachable connection called a stud connection. It is mostly utilized in those situations where one of the attached parts requires a compact structure or is often disassembled.
Screw: The screw
is a type of fastener that entails two pieces, those being the head and screw. There are, in turn, many different types of screws
, but for the skse of this article, we’ll categorize simply by if it's a special purpose screw, machine screw, or set screw. Special purpose screws are often used for elevating parts. Such an example can include items like eyebolts. The machine screw is often utilized as a tightly threaded part with a latched attachment connection. This latter piece has an opening in it. Lastly, the set screw is utilized to fasten the relative position between the two parts.
Bolt: A very common type of fastener, the bolt
is made up of a cylinder with an external thread and a head. These two pieces need to be attached with a nut so as to connect two pieces through holes. Once they are latched, this is called a bolted connection. Both parts can be separated so long as the nut is unscrewed from the bolt, in which case you can create a segment bolt or an expansion bolt.
Washer: A sort of clasp that is oblate, the washer
expands the contact surface territory of the associated part, and lessens the weight per unit zone to secure the outside of the associated part from damage. Most of the washers like this will act to keep the attachment from getting loose.
