Classification 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.
