Metric fastener is a very important engineering material, which has been used in many applications in different fields. Many industries use various types of Metric Fasteners, such as construction, wood processing, mobile and aerospace, and electronic equipment production.
However, in this particular content, I will introduce metric thread forming screws in particular. These are screws used to form material or base material around the hole until they are wrapped around the thread. As opposed to other metric screws, they do not remove any parts from the joint.
How do self tapping screws work?
In layman's terms, screw forming screws force the substrate or material to fit into its thread. The process is similar to self tapping screws (self tapping screws remove debris from the material), but they deform the substrate only by bending the substrate to the mating position without removing any of the joints.
application area
Metals or metallic materials - they can be used in a variety of metal materials, such as plate steel, sheet steel, non-ferrous metals and light metals; they can be used repeatedly (reuse).
Nylon and plastics - made from non-metallic materials, including acetals, polycarbonate, PVC and polypropylene.
Wood or wood material - re also has some types that can be specifically used for wood processing, such as in furniture and construction (e.g. m78007-ka18x5 Pt oval head steel zinc wn1412)
Analysis of the causes of rusty hardware screws: 1. When the electroplating factory is electroplating hardware screws, the drying is not done, resulting in residual water vapor. Or, after drying, condensate is formed during packaging. Dongguan Electronic Screw Factory introduces to you, it causes chemical reaction, produces bad occurrence, and causes hardware screw to rust. 2. Stored in a humid place for a long time. Over time, the hardware screws will slowly be corroded and oxidized, causing serious rust. 3. When electroplating hardware screws, the electroplating is poor, and the electroplating layer is too thin. Cause rust. All in all, analyze the reasons from four aspects. The four directions are: 1. Storage environment 2. Types of electroplating 3. How to save 4. Use environment. Therefore, we must pay attention to the key points in the use of stainless steel screws: 1. The surface of the stainless steel screw adheres to the organic juice (such as melon, vegetable, nood...
