When it comes to coated screws, ensuring their quality and reliability is essential for various industries and applications. Coating not only enhances the aesthetic appeal of screws but also provides protection against corrosion and improves their durability. To ensure the coated screws meet the desired standards, thorough inspection methods must be employed. This article explores the different…
Hexagonal wood screws , also known as hex wood screws, are a popular type of fastener used in woodworking, furniture making, and home repair projects. They come in various sizes, shapes, and materials, including steel, brass, and stainless steel. Today, we will discuss three common types of hexagonal wood screws: head wood screws, dowel screws, and self-tapping…
Flange screw mainly consists of hexagonal head, flange plate and screw stem, which needs to be matched with nuts, used to fasten and connect two parts with through-holes. Flange screws and bolts are widely used in highway and railway bridges, including industrial and civil construction, cranes, excavators and other heavy machinery. Commonly Used Flange Screws There are two kinds of hexagonal…
Both Bolts and Screws are common connection fasteners with similar threads that are widely used in many fields and equipment for connecting and fastening, this also is the main reason why many customers always mix them while purchasing. Now, here are several differences between bolts and screws that may help you choose the correct products. What…
Threads are an easy way to assemble multiple components (sheet metal, injection molded or CNC machined parts). The processing efficiency and quality of the thread will directly affect the processing quality of the parts and the production efficiency of the machining center. This article will introduce in detail what thread manufacturing methods are. Thread Cutting…
Screw thread is widely used in the connection of OCS components, which has the advantages of simple structure, reliable connection, convenient disassembly. However, it is easy to cause looseness of fasteners, so screw thread has great limitations in anti-loosening for OCS components. Current Situation Of Common Screw Thread Connection The ordinary screw threaded connection has self-locking function….
The torque test can determine the breaking torque, and it is mainly suitable for bolts and screws that cannot be tested for tensile tests. Note: Breaking torque is the torque at which the screw is sheared. What is a Torque Testing Machine? The torsion testing machine is used to measure the mechanical properties of metal…
Bolts are widely used in various industries and can be seen everywhere, so do you know the meaning of the grade marking on the bolts and screw thread? What Are the Performance Grades of Bolts The performance grade of bolts for steel structure connection can be divided into more than 10 grades, such as 3.6, 4.6,…
During routine inspection of threads, the general thread gauge cannot pass freely after surface coating treatment due to defects such as bumping on the surface of threads, such as electroplating and dacromet treatment, and butterfly threads cannot pass normally. Sometimes, the ring gauge can pass only after a certain amount of screwing torque is applied….
Whether it is furniture assembly or electrical assembly, it needs the help of screws to make them closely combined. The fixation effect of the hexagon socket head cap screws is good, and the applications is relatively wide. So what are the functions and advantages of hexagon socket head cap screws? Firstly, let’s learn what it is?…
