Why Choose Black Oxide Stainless Steel Machine Screw Nuts?
Our black oxide stainless steel machine screw nuts at AlbanyCountyFasteners.com, also known as black stainless machine screw nuts, are small, hexagonal nuts designed for precision fastening with machine screws in low-torque applications. Made from 18-8 (304, A2) stainless steel with a black oxide coating, these nuts offer enhanced corrosion resistance for wet or mildly corrosive environments, reduced light reflection, and a sleek, black aesthetic for decorative or low-visibility applications. The black oxide finish adds a protective layer while maintaining the strength of stainless steel. Available in imperial sizes like #0-80, #2-56, #4-40, #6-32 to #12-24, they meet ASME B18.6.3, IFI tolerances, REACH, and RoHS standards, making them ideal for electronics, automotive, and decorative projects requiring precision, corrosion resistance, and a modern look.
- Enhanced Corrosion Resistance: Black oxide over 18-8 stainless steel withstands wet environments.
- Precision Fastening: Small size ensures compatibility with machine screws for tight tolerances.
- Sleek Aesthetic: Black finish reduces glare and enhances visual appeal.
- High Standards: Compliant with ASME B18.6.3 for reliable performance.
Applications for Black Oxide Stainless Steel Machine Screw Nuts
Black stainless machine screw nuts are designed for projects requiring precise, corrosion-resistant fastening with machine screws, offering a decorative black finish for aesthetic or low-visibility needs. Their versatility makes them suitable for:
- Electronics and panel assemblies
- Automotive and motorcycle components
- Decorative hardware and furniture
- Outdoor fixtures in mildly corrosive settings
Frequently Asked Questions (FAQ)
Black oxide stainless steel machine screw nuts are small, hexagonal nuts made from 18-8 (304, A2) stainless steel with a black oxide coating, designed for precision fastening with machine screws, offering corrosion resistance and a sleek black finish.
How do black oxide stainless steel machine screw nuts differ from 18-8 stainless steel machine screw nuts?Black oxide stainless steel machine screw nuts have a black oxide coating for enhanced corrosion resistance, reduced glare, and a decorative black finish, while 18-8 stainless steel nuts have a bright, silver finish with standard corrosion resistance.
Are black oxide stainless steel machine screw nuts suitable for marine environments?They offer corrosion resistance in wet or mildly corrosive environments, but for marine or chloride-heavy settings, 316 stainless steel machine screw nuts are recommended for superior corrosion resistance.
How do I install black oxide stainless steel machine screw nuts?Thread the nut onto the machine screw and tighten with a wrench or pliers until secure. Use anti-seize compounds to prevent galling during installation.
How do I choose the right size black oxide stainless steel machine screw nut?Select based on the machine screw’s thread size, such as #4-40, #6-32, or #10-24. Ensure the nut’s thread pitch matches the screw. Check sizing charts or consult our team for guidance.
