M4 Stainless Steel SS ANSI A2 A4 70 80 Slotted Pan Head Screw Assembled With Washer Assortment

1,Description:

There are many names for bolts, and everyone's name may be different, some people are called screws, some people are called bolts, and some people are called fasteners. Although there are so many names, but the meaning is the same, are bolts. Bolt is a general term for fasteners. The bolt is a tool to tighten the parts step by step using the physical and mathematical principles of the inclined plane circular rotation and friction force of the object.

2,Applications:

Bolts are indispensable in daily life and industrial production and manufacturing, and bolts are also known as industrial meters. It can be seen that the use of bolts is wide.

The application range of bolts is: electronic products, mechanical products, digital products, power equipment, mechanical and electrical machinery products.

Bolts are also used in ships, vehicles, hydraulic projects, and even chemical experiments. Bolts are used in a lot of places anyway. Such as the precision bolts used in digital products. Miniature bolts for DVDS, cameras, glasses, clocks, electronics, etc. General bolts for televisions, electrical products, Musical Instruments, furniture, etc.; For projects, buildings and Bridges, large bolts and nuts are used; Transportation equipment, aircraft, trams, cars, etc., are used with large and small bolts. Bolts have important tasks in industry, and as long as there is industry on Earth, the function of bolts will always be important.

Marine environment equipment

Ship and offshore platform components**: 316 and 316L perform excellently in marine environments, making them commonly used for manufacturing ship parts and offshore drilling platforms that are exposed to saltwater.

Food processing equipment

Food transportation pipelines**: 316 stainless steel is used in pipelines that transport liquids and food, particularly in acidic or high-salt food production environments.

Medical devices

urgical instruments and implants**: Because 316L does not cause severe biological rejection and has high corrosion resistance, it is widely used to manufacture surgical instruments, orthopedic implants, and other devices in long-term contact with the body.

Pharmaceutical industry equipment

Pharmaceutical production containers**: Due to their corrosion resistance, easy cleaning, and low contamination risk, 316 and 316L are commonly used for reactors and storage tanks in the pharmaceutical industry.

- **Pipelines and transfer systems**: In pharmaceutical manufacturing, 316L is ideal for piping that transfers drug solutions and pharmaceutical-grade water, preventing corrosion during welding.

4,Feature Advantage:

Ordinary bolt head is very thick, difficult to deform, if vibration occurs after good, but also need to re-tighten; The flange with a thin part, can be slightly deformed, can be locked more firmly. There is also the fact that if it goes to the hole, the ordinary bolt can not use the tool, the head of the flange bolt is smaller, the following flange plate also plays a fastening role, but it can be used on the special tool to the hole, and the hexagonal bolt is about the same principle. Another is the flange top flat pad to use, in the softer, non-wear-resistant material is safer, will not cause perforation
