Frequently Asked Questions (FAQ)
Q: What is the difference between 304 and 316 expansion bolts?
A: 304 stainless steel is excellent for most outdoor and industrial uses. However, if your project is within 5 miles of the ocean, we recommend 316 stainless steel for its superior resistance to chlorides.
Q: Can you manufacture custom sizes?
A: Yes. We specialize in non-standard metal parts. Please send your technical drawings (STP/DWG) to our engineering team for a free quote.
