Frequently Asked Questions
Carbon steel inserts are typically plated with zinc or chrome and are best suited for softer, low-strength materials like plastics and aluminum. Stainless steel inserts (grades 303, 304, 316) offer superior strength and natural corrosion resistance, making them ideal for harsh, high-stress, or marine environments.
Plating carbon steel with zinc or chrome provides a protective barrier against oxidation and rust, extending the lifespan of the insert when used in non-corrosive or mildly damp environments.
Stainless Steel 316 contains molybdenum, which significantly enhances its resistance to chlorides and marine environments. Choose grade 316 for salt-water applications, chemical processing, or highly corrosive industrial settings.
Yes, carbon steel inserts are highly suitable for plastics, as well as copper and aluminum alloys, providing strong, wear-resistant threads in softer host materials.
Stainless steel inserts are widely utilized in marine engineering, aerospace, medical devices, electronic equipment manufacturing, and any application requiring high mechanical reliability and rust prevention.
