What are fasteners?

As a member of Chinese fastener manufacturers and distributors, Shimai has a deeper understanding of fasteners.Today, shimai will share an article about fasteners.

A fastener or fastening 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.It usually includes bolts, screws, nuts, wood screws, self-tapping screws, washers, pins, rivets, etc.

  1. Bolt

    A type of fastener consisting of a head and a screw (cylindrical body with external thread) needs to cooperate with a nut to fasten two parts with through holes. This form 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.A bolt is a form of threaded fastener with an external male thread. Bolts are very closely related to screws.

  2. Nut

    With internally threaded holes, the shape is generally a flat hexagonal column shape, or a flat square column shape or a flat cylindrical shape, with bolts, studs, or machine screws, used to fasten and connect two parts, making it a whole.

  3. Screw

    It is also a type of fastener composed of two parts, the head and the screw, which can be divided into three categories according to the purpose: machine screws, set screws and special purpose screws. The machine screw is mainly used for a tightening connection between a part with a threaded hole and a part with a through hole, which does not require a nut fit (this form of connection is called a screw connection and is also a detachable connection; it can also It is used with nuts to fasten the 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 bolts are used for lifting parts.

  4. Washer

    A type of fastener with an oblate ring shape. It is placed between the supporting surface of the bolt, screw or nut and the surface of the connected part, which increases the contact surface area of the connected part, reduces the pressure per unit area and protects the surface of the connected part from being damaged; another type of elastic washer, It can also prevent the nut from loosening.

  5. Pin

    It is mainly used for positioning parts, and some can also be used for connecting parts, fixing parts, transmitting power, or locking other fasteners.弹性销.jpgH359f4a6eea9b4d7dbbe487d6962e7a56G.jpgHcb8e3981ef114cc4bd11025b4208e288H.jpg_350x350.jpgphotobank (14).jpg

  6. Rivet

    A type of fastener consisting of a head and a nail rod is used to fasten and connect two parts (or components) with through holes to make it a piece. This form of connection is called rivet connection, or riveting for short. It is connected with non-removable. Because the two parts connected together must be separated, the rivets on the parts must be destroyed.

  7. Wood screw

It is also similar to machine screws, but the thread on the screw is a special thread for wood screws, which can be directly screwed into a wooden component (or part). It is used to connect a metal (or non-metal) part with a through-hole to a wooden component Tighten together. This connection is also detachable.
