Factory wholesale Black Oxide Stainless Steel Screws - SS316 DIN125A M6 Flat Washer –

Manufacturer M5 M6 M8 M10 Stainless Steel 304 316 DIN125 Flat Washer

Spring washers are used to prevent loosening, flat washers have no relaxation function, that is, flat washers only increase the contact area, and spring washers can prevent loosening.
Flat pads: just increase the surface area to prevent damage to the mounted parts of the soft substrate or to block the holes.

Spring pad: After locking, use the elasticity of the spring pad to prevent loosening

Product advantages:
Precision Machining
☆ Measure and process using precision machine tools and measuring tools under strictly controlled environmental conditions.

High-quality carbon steel
☆ With long life, low heat generation, high hardness, high rigidity, low noise, high wear resistance and other characteristics.

Cost-effective
☆ The use of high-quality carbon steel steel, after precision processing and forming, greatly improves the user experience.

Surface treatment:
BLACK
☆ Black is a common method for metal heat treatment. The principle is to make an oxide film on the metal surface to isolate the air and achieve rust prevention. Blackening is a common method for metal heat treatment. The principle is to make an oxide film on the metal surface to isolate the air and achieve rust prevention.

ZINC
☆ Electro-galvanizing is a traditional metal coating treatment technology that provides basic corrosion resistance to metal surfaces. The main advantages are good solderability and suitable contact resistance. Due to its good lubrication properties, cadmium plating is commonly used in aviation, aerospace, marine, and radio and electronic products. The plating layer protects the steel substrate from both mechanical and chemical protection, so its corrosion resistance is much better than zinc plating.

HDG
☆ The main advantages are good solderability and suitable contact resistance. Due to its good lubrication properties, cadmium plating is commonly used in aviation, aerospace, marine, and radio and electronic products. The plating layer protects the steel substrate from both mechanical and chemical protection, so its corrosion resistance is much better than zinc plating. Hot-dip zinc has good corrosion resistance, sacrificial protection for steel substrates, high weather resistance, and resistance to salt water erosion. It is suitable for chemical plants, refineries and coastal and offshore operating platforms.
