The difference between hot pressed nuts, hot melt nuts, in-mold injection nuts and threaded nuts
Hot-pressed nuts and hot-melt nuts are just called different things. They both use a soldering iron to penetrate the nut and press the nut into the injection molded part (the plastic part is partially melted through heat transfer through the nut). This kind of nut is usually made into a mesh. The plastic parts cannot be pulled out after being pressed into the plastic parts. When in-mold injection molding of nuts is performed, the nuts are first installed on the mold, and then the product is injection molded. In this type of injection molded product, an annular groove is cut on the outside of t

Screw is a popular term for fastening bolts. Here we focus on the discussion of screws in industrial products. There are two types of screws commonly encountered here: stainless steel screws and iron screws.
Classification and function of bolts
1. According to the force bearing mode of the connection: divided into ordinary and hinged holes. 2. According to the shape of the head: there are hexagonal head, round head, square head, countersunk head and so on. Among them, the hexagonal head is the most commonly used. Generally, countersunk heads are used where connections are required. 3. According to the tooth type of the thread, it is divided into two types: coarse tooth and fine tooth. The coarse tooth
What is the difference between the three concepts of bolts, screws, and screws?
In life, bolts, screws, screws, etc. are often mentioned, so what is the difference between them? In fact, the standard saying is that there are no screws and nuts. Screws are a common name, and those with external threads can be called "screws". The shape of the nut is usually hexagonal, and the inner hole is an internal thread, which is used to cooperate with the bolt and tighten the related parts. Nut is a common name, and the standard should be called "nut". The head of the bolt is generally hexagonal
The Difference Between Screws and Bolts
There is no difference between the two. Bolts are cylinders with external threads, and screws are pointed cylinders with external threads, both of which can be called screws. It needs to be matched with a nut to fasten two parts with through holes. This form of connection is called a bolt connection, and the nut can be unscrewed from the bolt to separate the two parts, so the bolt connection is a detachable connection. Bolts are cylinders with external threads, and screws are pointed cylinders with external threa
It's okay if the bolt is not loose, but it will break if it is loose? what is the reason?
Loosening of bolts is a common occurrence, but if you do not pay attention, it will often cause equipment vibration, component damage, and even casualties. How to tighten a small nut has always been an enduring topic in mechanical design. Everyone knows it well, such as Japanese eccentric nuts, Tang nuts and Chinese self-tightening king nuts, but we will not talk about these fasteners today. The star of the world, let's talk about the most basic method of fixing nuts at work. In general, we analyze bolt fracture
