5/16-18 C360 Brass Electronics Shoulder metal Bolt Anti-rust and anti-corrosion
1,Description:
Shoulder screw are also called shaft shoulder screws, stop screws, stop bolts, brake bolts, equal-height screws, etc. The shoulder screw is used in conjunction with the bolt pull rod and is mainly used as a mold accessory to control the opening stroke between the fixed mold seat plate, the runner push plate and the fixed mold template in the three-plate mold.
Because it can be set on the parting surface of the mold, the mold design can be miniaturized. This type of product features high hardness, good toughness, excellent wear resistance and heat resistance. It is suitable for precision molds and can significantly extend their service life. Especially, the thermal deformation of precision molds has been effectively controlled, making it suitable for molds in high-temperature working environments Its standard is ISO 7379. The material of the 12.9 grade plug screw is SCM435 alloy steel, with an overall hardness of HRC40°

It is suitable for precision molds and helps to extend their service life, especially playing a certain role in controlling the thermal deformation of precision molds. It is applicable to molds in high-temperature working environments.
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
Copper Cu:58.0-61.0 Iron Fe:0.3 Lead (Pb) :1.5-2.5 Zinc (Zn) : Surplus.
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.
Manufactured by JIA SHAN Hardware Company with strict quality control measures and pre-shipment inspection.
