FAQS on steel carriage bolt

Q: What is the difference between stainless steel and regular steel carriage bolts?

A: Stainless steel carriage bolts offer superior corrosion resistance due to their chromium content, making them ideal for outdoor or humid environments. Regular steel carriage bolts are stronger but may require coatings to prevent rust.

Q: What does "1/4-20" mean in a stainless steel carriage bolt?

A: "1/4-20" refers to a 1/4-inch diameter bolt with 20 threads per inch, a common imperial thread size. This specification ensures compatibility with matching nuts and pre-tapped holes in assemblies.

Q: Are stainless steel metric carriage bolts suitable for marine environments?

A: Yes, stainless steel metric carriage bolts (especially grades like 316) resist saltwater corrosion effectively. They’re widely used in marine applications but require periodic maintenance in extreme conditions.

Q: Can stainless steel carriage bolts handle high-temperature applications?

A: Grade 304 stainless steel carriage bolts can withstand temperatures up to 870°C (1600°F), while grade 316 tolerates slightly lower heat. Both outperform regular steel bolts in thermal resistance.

Q: How do I choose between imperial and metric stainless steel carriage bolts?

A: Select based on your project's measurement system—imperial (e.g., 1/4-20) for North American machinery, metric (e.g., M6) for European/ISO-standard equipment. Verify thread compatibility with existing components.
