Stainless steel bolts, stainless steel nuts, stainless steel screws, can be customized, complete variety
Material classification
There are many choices of materials for stainless steel bolts and nuts, the common ones are:
SUS201: also known as stainless iron, suitable for environments with low anti-rust requirements.
SUS304 (A2-70): widely used material with good corrosion resistance and rust resistance, and moderate price.
SUS316 (A4-70): suitable for highly corrosive environments such as chemical and marine environments.
SUS316L: has excellent corrosion resistance and is often used in the chemical industry.
Types and standards
There are many types of stainless steel bolts and nuts, the common ones are:
Hexagonal bolts: including half-threaded hexagonal bolts and full-threaded hexagonal bolts, the standard numbers are national standard GB5782, German standard DIN931, American standard ANSI/ASME B18.2.1, etc.
Hexagonal nuts: including hexagonal nuts, hexagonal thin nuts, hexagonal fine-thread nuts, etc., with standard numbers including national standard GB6170, German standard DIN934, American standard ANSI/UNC, etc.
Application scenarios
Stainless steel bolts and nuts are widely used in various occasions requiring high strength and corrosion resistance, such as:
Chemical equipment: used to connect and fix various components in chemical equipment.
Marine engineering: suitable for equipment and structures in marine environments, such as offshore platforms and ships.
Building structure: used for exposed parts of buildings such as bridges and high-rise buildings to prevent corrosion and rust.
