5/8-11 Grade 8 Carbon Steel Automotive Shoulder metal Bolt High Tensile Black plain
1,Description:
Shoulder screws are also referred to as shaft shoulder screws, stop screws, stop bolts, brake bolts, equal-height screws, among other names. The shoulder screw works together with the bolt pull rod and serves primarily as a mold component to regulate the opening stroke between the fixed mold base plate, the runner stripper plate, and the stationary mold plate in three-plate molds.
Since it can be positioned on the mold parting surface, the mold design can be made more compact. This product type exhibits elevated hardness, superior toughness, outstanding abrasion resistance, and thermal stability. It is well-suited for high-precision molds and can substantially prolong their service life. In particular, the thermal expansion of precision molds is effectively managed, rendering it appropriate for molds operating in elevated-temperature conditions. Its specification follows ISO 7379. The material for the 12.9 grade plug screw is SCM435 alloy steel, with a comprehensive hardness of HRC40°.
The shoulder screw operates in combination with the bolt pull rod and functions chiefly as a mold accessory to govern the opening distance between the fixed mold seat plate, the sprue ejector plate, and the fixed mold template in three-plate mold configurations.
Owing to its ability to be mounted on the mold parting surface, the mold architecture can be downsized. This category of product demonstrates high rigidity and ductility, coupled with excellent wear endurance and heat tolerance. It is appropriate for precision tooling and contributes to extending their operational lifespan, notably exerting a certain influence on managing the thermal distortion of precision molds. It is applicable to tooling utilized in high-temperature working settings.
2,Applications:
Screws are widely used in the industrial field. From large items like spaceships and aircraft to small ones like mobile phones and tables and chairs, they are indispensable. Therefore, they are also known as the "rice of industry".
How important is that tiny screw to an aircraft? According to the data, the Boeing 747There are approximately over 6 million parts in the series of aircraft, and among these parts, fastenersThe proportion accounts for half.There are also quite a few flight safety accidents caused by screw problemsIf experts analyze that one of the reasons for the emergency landing of Sichuan Airlines Flight 3U8633 is very likely to be that the screws of the windshield were substandard or excessive force was applied during installation, which led to cracks in the windshield. It finally falls off.
3,Technical Advantages
The machinability grade is 100, the tensile strength reaches 68,000 psi, and it has excellent corrosion resistance and oxidation resistance
Due to its unique properties, such as a machinability grade of 100, tensile strength reaching 68,000 psi, and excellent corrosion and oxidation resistance, this alloy is suitable for Marine and industrial environments. Application solution: C360 brass is a versatile material that is widely used in various industries due to its durability, machinability and corrosion resistance. Common applications include piping installations, screw machine parts, electrical components and Marine hardware, making it an ideal choice for industrial and harsh environments.

Lead brass is an extremely important and widely used type of complex brass. It features excellent machinability, wear resistance and high strength. It is mainly used in various connecting parts, valves and valve stem bearing cages in mechanical engineering. Among them, hot forging valve blanks, the lockmaking industry and the watch industry are the three major important markets. The low cost of lead brass is an important prerequisite for its wide application. Its alloy composition can contain various alloying elements, and the content requirements are relatively loose, which also lays a foundation for the comprehensive utilization of copper alloy raw materials.
Available in small packing, carton packing, or pallet configurations to meet your shipping and storage requirements.
