Product Description

Product Description

External hexagon screw combination is a common fastener, characterized by combining screws, spring washers, and flat washers together, without the need to separately equip these components during use, simplifying the installation process. The main materials of the external hexagonal screw combination include iron and stainless steel, among which stainless steel material can maintain stable performance even in harsh environments due to its good corrosion resistance and strength.
The advantages of the combination of external hexagonal screws
1. Simplified installation process * *: Combination screws pre assemble screws, spring washers, and flat washers together, eliminating the need for separate assembly during use, saving installation time.
2. Anti loosening function: The design of the combination screw increases the anti loosening performance, ensuring that the connection remains stable under various conditions.
3. High strength and stability: Stainless steel hexagonal flange screws play an important role in multiple industries due to their unique design and superior performance. This type of screw has better stability and load-bearing capacity when connected.
The purpose of the external hexagonal screw combination
1. In the field of architecture: used to connect various structural components, such as steel structures, curtain walls, etc.
2. Mechanical manufacturing: used to connect mechanical components such as bearings, gears, etc.
3. Electronics industry: Various components used to connect electronic devices, such as circuit boards, heat sinks, etc.
4. Shipbuilding: Used to connect various structural components of ships, such as decks, hulls, etc.
5. Automotive manufacturing: used to connect various components of a car, such as the engine, chassis, etc.
When selecting a combination of hex screws, the required material and strength grade should be determined based on the specific application environment and requirements. For example, in places such as buildings and bridges that require high strength and heavy performance, external hexagonal bolts of grade 10.9 or above are generally chosen.
