M2.5 M5 ASTM B7 B7M Stainless Steel Male And Female Hexagon Head Metal Standoff single studs
Product Description:
What is a standoff? As the name suggests, tstandoff is one end for the internal thread and the other end for the external thread of a kind of screws, broadly speaking, standoff also include both ends are internal thread screws. Its appearance is hexagonal, play a role in fastening and isolation, because it is generally used hexagonal copper rod as raw material production and become, so tstandoff is also known as copper column, hexagonal copper column, copper isolation column or copper spacer column.
The use of standoff. Intercalated screws are mainly used in the computer, circuit board and other industries, when one end is screwed into the locked object, the hexagonal post is exposed to the outside, which can fix or isolate other objects.
The main specifications of standoff are M3, M4, M5, M6, M8, M10, etc., and their hexagonal posts were 5, 6, 8, 10, 12, 15mm, etc., which should be in the most or the M3 series. Material in addition to copper an
Hexagonal studs are also known as yin and yang studs, it is one end of the internal thread and one end of the external thread, but are hexagonal, can play a role in fastening and isolation.
Mostly used in computers, circuit boards and other industries, when used, when one end is screwed into the workpiece being fastened, the hexagonal column is exposed on the surface, can be fixed or isolated from other workpieces. Such as in the computer mainframe, the external thread can be connected to the motherboard inside the mainframe, the internal thread can be isolated from the motherboard and sheet metal shell.

Stainless Steel:
1, the basic knowledge of stainless steel
Stainless steel is an alloy material with corrosion resistance, and its main components are an alloy of elements such as iron, chromium and nickel. These elements can effectively resist oxidation and corrosion, so that stainless steel has a high degree of durability and aesthetics.
2, stainless steel maintenance methods
Cleaning
Keeping stainless steel products clean is an important part of their maintenance. You can use mild detergents and soft cloth for cleaning, avoid the use of detergents containing acidic and alkaline components, so as not to damage the surface of stainless steel. When removing dirt, you should try to avoid using irritating cleaning tools to avoid scratching the stainless steel surface. After cleaning, rinse with water and dry with a clean soft cloth.
3, the use of stain remover
For some stubborn dirt, you can use special stainless steel stain remover for cleaning. But before using it, you should carefully read and follow the instructions in the product manual. In addition, stainless steel products on the dirt can be cleaned with alcohol or vinegar, these common cleaners on stainless steel has a certain decontamination effect.

Stainless steel is renowned for its excellent resistance to corrosion. This is primarily due to the presence of chromium in its composition, which forms a thin, self-healing oxide layer on the surface. This layer protects the steel from rust and other forms of corrosion. This property makes stainless steel ideal for use in harsh environments, such as marine applications, chemical processing, and food processing industries, where exposure to moisture, salt, or chemicals is common.
Stainless steel is incredibly strong and durable. It can withstand significant mechanical stress and maintain its structural integrity over long periods. Its high tensile strength and yield strength make it suitable for applications that require robust materials. It is commonly used in construction (e.g., structural beams, reinforcement bars), automotive manufacturing (e.g., exhaust systems, chassis components), and industrial machinery (e.g., gears, shafts).
Stainless steel has a sleek, shiny appearance that is both visually appealing and easy to maintain. It can be polished to a mirror finish or textured to achieve different looks. It is widely used in consumer products (e.g., kitchen appliances, cutlery, sinks), architectural elements (e.g., handrails, decorative panels), and medical devices (e.g., surgical instruments) where appearance is important.
Stainless steel is non-porous and easy to clean, making it highly suitable for applications where hygiene is critical. Its smooth surface resists the buildup of bacteria, mold, and other contaminants. It is extensively used in the food and beverage industry (e.g., food processing equipment, dairy machinery), pharmaceutical industry (e.g., clean rooms, laboratory equipment), and healthcare (e.g., hospital equipment, surgical tools) where maintaining cleanliness is essential.
Stainless steel can withstand high temperatures without significant degradation. It maintains its strength and stability even in high-heat environments, making it suitable for applications involving thermal processes. It is used in industrial furnaces, heat exchangers, and automotive exhaust systems, where it can resist oxidation and scaling at elevated temperatures.
