Stainless steel 304 lead sealed bolts are fasteners with specific purposes, mainly used to prevent bolt loosening or illegal disassembly. This type of bolt usually has holes for sealing with lead sealing wire, ensuring that it will not be easily opened or tampered with during application.
Here are some detailed information about stainless steel 304 lead seal bolts:
Stainless steel 304 lead seal bolts are mainly made of AISI 304 stainless steel, which has good corrosion resistance and strength. Common specifications include different sizes such as M3, M4, M5, M6, etc., with lengths ranging from a few millimeters to tens of millimeters.
This type of bolt is widely used in devices such as electricity meters, water meters, gas meters, and fuel dispensers to prevent unauthorized personnel from opening or tampering with parameters. In addition, it is also used in industrial manufacturing, shipbuilding, aviation, petrochemicals and other fields to improve the safety and reliability of equipment.
Stainless steel 304 lead sealed bolts are usually designed with a hexagonal tail with holes, which allows for easy threading and knotting of lead sealing wires to achieve a sealing effect. Some products also offer galvanizing treatment to enhance their corrosion resistance.
01
Materials and Manufacturing Processes
Stainless steel 304 lead seal bolts are mainly made of 304 stainless steel material, which has good corrosion resistance and mechanical properties. Its manufacturing process includes two methods: cold forging and hot forging. During the cold forging process, the 304 stainless steel blank is heated to around 700 ℃, then rapidly cooled to harden it, and then forged using a cold forging machine to reduce internal defects and improve strength.
02
Specification and Model
The common specifications of 304 stainless steel lead seal bolts range from M3 to M24, suitable for different application needs. In addition, there are various models available, such as DIN912 hexagonal tail with perforated lead seal screws, M5 × 10, etc.
03
application area
Due to its excellent rust and corrosion resistance, 304 stainless steel lead seal bolts are widely used in various fields such as chemical, military, mechanical, aerospace, aviation, nuclear power, shipbuilding, marine, curtain wall, etc. Especially in situations where illegal disassembly and tampering are required, such as in electric meter boxes and swimming pool water treatment equipment, this type of bolt is particularly important.
04
surface treatment
In order to meet the needs of different usage environments, 304 stainless steel lead sealed bolts can undergo various surface treatments, such as cleaning and passivation, nickel plating, color zinc plating, copper plating, etc. These treatments not only improve the aesthetics of the bolts, but also enhance their corrosion resistance and service life.
