Service HotlineThe material of the round head three OttawaOttawaOttawacombination screw is divided into iron and stainless steel. The iron ones are made of different iron screw wires. Generally, the wire of the OttawaOttawaOttawacombination screw is 1010, 1018, 10B21 and so on. 10B21 is used to make 8.8 grade OttawaOttawaOttawacombination screws. Like 8.8-grade socket head Ottawacap screws, 10B21 wires are often used to make them. When done, go to heat treatment. After heat treatment, remove hydrogen and electroplating. This is to prevent the OttawaOttawaspring washer of the socket head Ottawacap screw from breaking. Stainless steel OttawaOttawaOttawacombination screws, in the OttawaOttawaOttawacombination screw market, generally refer to stainless steel SUS304 OttawaOttawaOttawacombination screws. 201 OttawaOttawaOttawacombination screws generally do very little. Few manufacturers of round head three OttawaOttawaOttawacombination screws produce 201 OttawaOttawaOttawacombination screws. Because the hardness of the screw wire of stainless steel 201 is not well controlled, it is easy to produce cracks. Introduction to the basic knowledge of electroplating round head OttawaOttawaOttawacombination screw electroplating generally refers to the de-plating of iron OttawaOttawaOttawacombination screws. Electroplating is divided into environmental protection and non-environmental protection.

The installation of the pressure riveting nut is exquisite. If the installation method is not correct, the riveting will not be firm after the pressure riveting. For example, one of our customers reported that the nut would fall off after riveting. Our technicians found that many customers hit it with a hammer or other impact methods, because the installation method of the riveting nut will cause pressure. The uneven force of the OttawaOttawarivet nut seriously affects the riveting effect. It looks like it is pressed in on the surface, but in fact, the flower teeth of the OttawaOttawarivet nut are not riveted with the plate at all, so it is definitely not riveted. To install the OttawaOttawarivet nut, you must use special installation equipment, or simply install it with a press and stamping equipment (generally factories will have these simple equipment).
