Stainless Steel Fasteners

Stainless steel fasteners are a specific professional term concept that includes a wide range of products. Stainless steel fasteners are usually used to fasten more expensive machine parts because of their appearance, durability, and strong corrosion resistance.

1. Bolt: A type of fastener consisting of a head and a screw (a cylinder with an external thread). It needs to be matched with a nut and is used to fasten two parts with through holes. This type of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

 

2. Stud: A type of fastener that has no head and only has external threads on both ends. When connecting, one end of it must be screwed into the part with an internal thread hole, the other end must pass through the part with a through hole, and then the nut is screwed on, even if the two parts are tightly connected as a whole.

3. Screws: They are also a type of fasteners composed of two parts: a head and a screw. They can be divided into three categories according to their uses: machine screws, set screws and special-purpose screws. Machine screws are mainly used for parts with a tightening threaded hole. The fastening connection with a part with a through hole does not require nut cooperation (this form of connection is called a screw connection and is also a detachable connection; it can also be used with Nut fit, used for fastening connection between two parts with through holes.) Set screws are mainly used to fix the relative position between two parts. Special-purpose screws such as eye screws are used for lifting parts.

4. Stainless steel nuts: with internal threaded holes, generally in the shape of a flat hexagonal cylinder, or flat square cylinder or flat cylinder, used with bolts, studs or machine screws to fasten two parts. Make it a whole piece.

5. Self-tapping screws: Similar to machine screws, but the threads on the screw are special threads for self-tapping screws. It is used to fasten and connect two thin metal components to make them into one piece. Small holes need to be made in advance on the structure. Since this kind of screw has high hardness, it can be directly inserted into the hole of the component to make the component in the middle. Forms responsive internal threads. This type of connection is also a detachable connection.

 

6. Washer: A type of fastener that is shaped like an oblate ring. Placed between the supporting surface of bolts, screws or nuts and the surface of the connected parts, it plays the role of increasing the contact surface area of the connected parts, reducing the pressure per unit area and protecting the surface of the connected parts from being damaged; another type of elastic washer, It can also prevent the nut from loosening. 

7.Pins: Mainly used for positioning parts, and some are also used for connecting parts, fixing parts, transmitting power or locking other fasteners.

 

8. Rivet: A type of fastener consisting of a head and a nail shank, used to fasten and connect two parts (or components) with through holes to make them a whole. This form of connection is called rivet connection, or riveting for short. Belongs to a non-detachable connection. Because in order to separate two parts that are joined together, the rivets on the parts must be broken.

 

9.Welding nails: Because of the heterogeneous fasteners composed of light energy and nail heads (or no nail heads), they are fixed and connected to a part (or component) by welding method so that they can be connected to other stainless steel standard parts.
