Custom Screws Manufacturer Shi Shi Tong

A customer from the United States contacted us while developing a sanitary processing system.The screws were used to secure the machine cover and rack assembly.At first glance, a standard 304 stainless steel screw appeared to be sufficient.
However, after discussing the actual application, the customer identified several concerns.The equipment required frequent cleaning and regular maintenance.Operators needed to remove and reinstall the covers repeatedly throughout the equipment's service life.At the same time, the fastening points remained visible on the exterior of the machine, making appearance an important consideration.A standard screw could provide basic fastening, but it could not fully address the maintenance challenges behind the application.If the screw head was difficult to access, maintenance efficiency would decrease.If the drive recess became damaged after repeated servicing, replacement costs would increase.For this project, we did not immediately recommend a screw after reviewing the drawing.
Before recommending a solution, we reviewed maintenance frequency, cleaning procedures, installation conditions, appearance requirements, and production plans.At Shi Shi Tong, we help customers evaluate structure design, material selection, surface treatment, manufacturability, inspection requirements, and production consistency.After evaluating the application, we recommended a customized 304 stainless steel screw solution.The head design improved accessibility during maintenance, while the drive recess reduced stripping during repeated assembly and disassembly.The surface finish helped maintain a clean and consistent appearance suitable for sanitary equipment.As a result, the customer achieved easier maintenance, improved appearance consistency, and more reliable long-term fastening performance.
For us, a custom fastener project does not begin with the screw size. It begins with understanding how the equipment will actually be used and maintained.We do not simply make screws. We help customers make sure the screw truly fits the application.

304 Stainless Steel Screw: Is It Really Non-Magnetic?

When discussing stainless steel screw solutions with customers, one question comes up again and again: "If it's 304 stainless steel, why is it magnetic?" 🤔

The truth is that 304 stainless steel is generally considered non-magnetic, but cold working during manufacturing can introduce slight magnetism. In many applications, it can also be demagnetized to meet specific requirements.

✅ Key Benefits of 304 Stainless Steel Screws

Excellent corrosion resistance
Suitable for electronics, medical devices, food equipment, and precision assemblies
Available in customized sizes, head types, and thread designs
Optional demagnetization process for special applications

💡 Why Customers Choose Custom 304 Screws
✔ Stable material quality and traceability
✔ Custom solutions for non-standard requirements
✔ Support for non-magnetic and high-precision applications
✔ OEM & ODM manufacturing available

📩 Looking for custom 304 stainless steel screws or have questions about magnetic properties? Feel free to send us a message. Our engineering team is happy to help find the right solution for your project.
