Product Description


The  Carriage  bolt  is Black Oxide DIN6921 GB5787 ASME B18.2.1.8 Hex Flange Screw Gr 10.9. Its shank is threaded. By being used in conjunction with nuts and taking advantage of the frictional and mechanical interlocking effects of the threads, it applies clamping force to two or more components in various mechanical connection and building structure scenarios, thus achieving a stable connection.

CUSTOMER  Q & A--



 
**01 Why is stainless steel sometimes magnetic?**  

304 stainless steel is an austenitic stainless steel. During cold processing, part of the austenite transforms into martensite. Martensite is magnetic, which is why 304 stainless steel is generally non-magnetic or only weakly magnetic. For details, search online for "Why is 304 stainless steel magnetic?"  

---

**02 How to identify authentic 304 stainless steel products?**  

1. Use **304-specific testing solution**: No color change indicates authentic 304 stainless steel.  
2. Conduct **chemical composition analysis** or **spectral analysis**.  
3. Perform a **smoke test** to simulate real-world usage conditions.  

---

**03 What are the common types of stainless steel?**  

1. **201 stainless steel**: Suitable for dry environments; prone to rusting when exposed to rain.  
2. **304 stainless steel**: Ideal for outdoor or humid environments due to high corrosion resistance, acid resistance, and strength.  
3. **316 stainless steel**: Offers superior corrosion and acid resistance, especially suitable for seawater and chemical environments.
