Global standards for stainless steel screws:

1. ISO standards: The International Organization for Standardization (ISO) has developed a series of standards for stainless steel fasteners, such as the ISO 3506 series. These standards cover the dimensions, materials, mechanical properties and other indicators of stainless steel bolts, screws, studs and other fasteners. For example, ISO 3506-1:2020 specifies performance levels for bolts, screws and studs in austenitic, martensitic, ferritic and duplex stainless steel grades and applies to ISO metric threaded fasteners of any shape.

2.DIN standards: The German National Organization for Standardization (DIN) has also formulated corresponding stainless steel fastener standards, such as DIN 931 and DIN 933. Mainly used in the European market, these standards specify the size, material and mechanical properties requirements for stainless steel bolts.

3. ASTM standards: The American Society for Testing and Materials (ASTM) has developed multiple standards for stainless steel fasteners, such as ASTM F593-22. Mainly used in the North American market, these standards regulate the quality, chemical composition and mechanical properties of stainless steel bolts, screws and studs.

4. GB standards: Chinese national standards (GB) also provide detailed regulations for stainless steel fasteners, such as GB/T 3098 series. These standards cover the mechanical properties of stainless steel bolts, screws and studs and are consistent with international standards.

5. Other international standards: In addition to the above-mentioned main standards, there are other international standards such as JIS (Japanese Industrial Standards), BS (British Standards), etc. These standards are also widely used in their respective countries and regions.

Common pairings of stainless steel screws:

1. Pairing of the same material: In order to prevent corrosion, stainless steel bolts are usually used with nuts and washers of the same material. For example, 304 stainless steel bolts can be used with 304 stainless steel nuts, or 316 stainless steel bolts can be used with 316 stainless steel nuts. This pairing method can effectively avoid the problem of electrochemical corrosion

2. Pairing of different materials: In some cases, stainless steel bolts can also be used with nuts of different materials, such as a combination of 304 stainless steel bolts and 316 stainless steel nuts. This pairing requires consideration of components with the least corrosion resistance and may increase the risk of thread seizure, so it is recommended to consult an experienced fastener material expert.

3. Pairing of components: Stainless steel bolts are often used in combination with corresponding washers and spring washers to improve the fastening effect and prevent loosening. For example, stainless steel combination screws that combine stainless steel cross recessed pan head screws with flat washers, external serrated locking washers, and spring washers.

4. Special application pairing: In high temperature and high pressure environments, stainless steel bolts may not be able to withstand the amount of shrinkage caused by temperature differences, so alloy steel bolts are usually required in this case. Additionally, where galvanized or other non-stainless steel parts are involved, it is recommended to use spacers to avoid galvanic corrosion.
