FAQs

1. What are the primary advantages of brass inserts over steel alternatives?

Brass inserts offer superior corrosion resistance in humid and marine environments, excellent thermal and electrical conductivity for electronics applications, easier machining and installation, and non-magnetic properties for sensitive equipment. Steel inserts provide higher strength but may require additional corrosion protection coatings.

2. Can brass inserts withstand high-temperature industrial applications?

Yes, brass inserts maintain structural integrity and thread strength at continuous operating temperatures up to 200°C (392°F). For extreme temperature applications exceeding 250°C, BOLTORQ Brassmet offers specialized high-temperature brass alloys and can recommend alternative materials like stainless steel inserts.

3. How do I choose the right brass insert for my application?

Consider factors such as the type of material, environmental conditions, and specific requirements of your application. Consulting with BOLTORQ Brassmet’s customer service can also help you make the right choice.

4. Can brass inserts be used in outdoor and marine environments?

Absolutely. Brass alloys demonstrate excellent performance in outdoor installations and marine applications due to natural corrosion resistance. For severe marine environments, BOLTORQ Brassmet recommends nickel-plated brass inserts providing enhanced protection. Salt spray testing validates 1000+ hour corrosion resistance per ASTM B117 standards.

5. Do brass inserts require special maintenance?

Brass inserts are low-maintenance but should be regularly inspected for any signs of wear or damage. Cleaning them periodically will help maintain their appearance and performance.

By choosing BOLTORQ Brassmet, you are investing in inserts that combine quality, durability, and exceptional performance, ensuring the success of your projects for years to come.
