Summary of information:We have more than ten years of production experience in the screw industry, the main products are: dish washers, flat he...

nut is a nut, a part that is screwed together with a bolt or screw for fastening. A component that must be used in all production and manufacturing machinery is divided into carbon steel, stainless steel, non-ferrous metals (such as copper), etc. several types. Chinese name nut Foreign name Crewnut alias Nut properties and bolts or screws screw together to tighten the role of carbon steel, stainless steel, non-ferrous metal standard GB German standard international standard Japanese standard American standard features Steel, stainless steel, copper, alloy, etc.

Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with an external thread), which needs to be matched with a nut to fasten and connect two parts with through holes. This form of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

The four corners of the bolt head of the traditional T-slot connection bolt are all rounded corners, which will make the contact area between the bolt and the T-slot too small and reduce the connection fastness, especially when used for connection. When aluminum or copper profiles are used, due to the low hardness of the material, it is more likely to cause deformation of the T-shaped groove and affect the connection effect. Furthermore, since the traditional T-bolt has no direction indicator, it is difficult for the installer to identify the installation state during installation.

High-strength self-locking nut for boats and bridges, it can convert the friction force into the expansion force between the bolt and the slot nut to achieve excellent self-locking effect. There are two slots on the upper part of the ESL nut. When the nut is tightened on the bolt, the thread of the bolt will be screwed into the slot of the cross section of the nut, and the thread will be gradually locked by the side wall of the nut to achieve the function of self-locking. The exquisite production process can keep the torque type of the locking element consistent, and the products are generally used in railway casting, rail transit, transmission system, mining equipment, highway, military, oil production machinery, automobile industry, public facilities, subway, engine, construction machinery , aerospace, drilling equipment, bridges, generators, agricultural machinery, shipbuilding industry, metallurgical equipment, trains, compressors, medical machinery, signal systems, wind power generation

In view of the deficiencies of the prior art, Guangdong Yueluo Hardware Industry Co., Ltd. provides a relatively simple screw that can be manually disassembled. In order to achieve the above purpose, Guangdong Yueluo Hardware Industry Co., Ltd. provides the following technical scheme: a screw that can be disassembled manually, including a stud and a nut, and the axial direction of the screw is provided with a screw extending from the nut to the stud. A groove, a control column that is slidably matched with the groove is arranged in the groove, a through groove is opened on the circumferential side wall of the control column, and a circumferential side wall of the control column is provided with a parallel to the axis of the control column. A limit bar, the side wall of the groove is provided with a limit groove that cooperates with the limit bar, the control column is provided with a accommodating groove, and the accommodating groove is provided with a rotating rod that cooperates with the through groove, so The accommodating groove and the rotating rod are arranged separately. Further, a accommodating groove is opened at the corresponding groove on the nut, a baffle is hinged on the side wall of the accommodating groove, and a torsion spring is provided at the hinged joint between the baffle and the accommodating groove.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: wheel bolts, hexagonal copper studs, disc nuts, Dacromet-plated double-stacked self-locking washers and other products, we can provide you with suitable products for you fastener solutions.
