Summary of information:We have more than ten years of production experience in the screw industry. The main products are: 620 cylinder head bol...

Washers are accessories used between the nut and the connecting piece to disperse the pressure of the nut on the connected piece, thereby protecting the connected piece. The general gasket is a flat gasket, which is easy to loosen after long-term use, and the stability is not high. There are also some elastic washers, which have poor elastic stability and short service life.

There are two types of bolt detection: manual and machine. Manual is the most primitive and the most commonly used consistent detection method. In order to minimize the outflow of defective products, general production enterprise personnel inspect the packaged or shipped products by visual means to exclude defective products (defects include tooth damage, mixed materials, rust, etc.). [2] Another way is automatic machine inspection, mainly magnetic particle inspection. Magnetic particle inspection is to use the interaction between the leakage magnetic field at the defect of the bolt and the magnetic powder, aiming at the difference between the magnetic permeability of the bolts (such as cracks, slag inclusions, mixed materials, etc.) and the magnetic permeability of steel, these materials are discontinuous after magnetization. The magnetic field at the place will be turbulent, and a leakage magnetic field will be generated on the surface of the workpiece where part of the magnetic flux leaks, thereby attracting the magnetic powder to form the magnetic powder accumulation at the defect—magnetic traces. The accumulation of these magnetic powders is observed and explained, and the purpose of rejecting defective products has been achieved.

The advantages of Guangdong Yueluo Hardware Industry Co., Ltd. are that the rivet nut is fixed on thin-walled or thin-plate objects without welding, easy operation, high production efficiency, easy to manufacture, low cost, single-sided riveting, firm connection, no pollution, no noise, Has significant economic benefits.

Screw refers to a screw, which is a tool that uses the physical and mathematical principles of the inclined plane, circular rotation and friction of an object to gradually fasten objects and parts. A screw is a common term for fasteners. Fasteners are widely used in machinery, electrical appliances and buildings. They are generally made of metal or plastic, cylindrical in shape, and grooves engraved on the surface are called threads.

The hexagonal nut is used in conjunction with screws, bolts and screws to connect and fasten parts. Among them, the Type 1 six-purpose nut is the most widely used. The C-level nut is used for machines, equipment or structures with rough surface and low precision requirements; A-level and B-level nuts are used for relatively smooth surfaces and high precision requirements. machine, equipment or structure. The thickness M of the type 2 hexagon nut is thicker, and it is mostly used in occasions where assembly and disassembly are often required. The thickness M of the hexagonal thin nut is relatively thin, and it is mostly used in situations where the surface space of the connected parts is limited.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: black grade 8 washers, non-slip anti-skid nuts, hand percussion aluminum rivets, plum blossom screws and other products, we can provide you with suitable products for you fastener solutions.
