Why Choose Black Oxide Stainless Steel Hex Jam Nuts?
Our black oxide stainless steel hex jam nuts at AlbanyCountyFasteners.com, also known as black oxide jam nuts, are low-profile hex nuts, about 2/3 the thickness of standard hex finish nuts, designed for locking or space-constrained applications. Featuring a hexagonal shape for easy gripping with a wrench or pliers, these nuts are made from 18-8 stainless steel (equivalent to 304) with a black oxide coating, offering corrosion resistance, a sleek, non-reflective black finish, and anti-galling properties. They are tightened against another nut to lock without clamping, using the “double nut” method. Available in imperial sizes like #6-32, #8-32, #10-24, 1/4"-20 to 1"-8, they meet ASME B18.2.2, DIN 439B, ISO 4035, IFI tolerances, REACH, and RoHS standards and are ideal for automotive, machinery, and decorative projects requiring corrosion resistance and a refined aesthetic.
- Corrosion Resistance: 18-8 stainless steel with black oxide coating ensures durability in wet environments.
- Sleek Aesthetic: Non-reflective black finish enhances visual appeal.
- Low Profile: Thinner design fits tight spaces where standard nuts won’t.
- High Standards: Compliant with ASME B18.2.2 and DIN 439B for reliability.
Applications for Black Oxide Stainless Steel Hex Jam Nuts
Black oxide jam nuts are designed for projects requiring a low-profile, corrosion-resistant locking solution with a refined black finish, used with bolts or screws to secure assemblies or fit tight spaces. Their versatility makes them suitable for:
- Automotive and motorcycle assemblies
- Decorative hardware and furniture
- Industrial machinery and equipment
- Outdoor and architectural fixtures
Frequently Asked Questions (FAQ)
Black oxide stainless steel hex jam nuts are low-profile, hexagonal nuts made from 18-8 stainless steel with a black oxide coating, used as locknuts by tightening against another nut or in tight spaces, offering corrosion resistance and a sleek finish.
How do black oxide stainless steel hex jam nuts differ from 18-8 stainless steel hex jam nuts?Black oxide stainless steel hex jam nuts feature a black oxide coating for a non-reflective finish and anti-galling properties, while 18-8 stainless steel hex jam nuts have a natural silver finish without the coating’s aesthetic or functional benefits.
Are black oxide stainless steel hex jam nuts suitable for marine environments?They resist corrosion in wet environments, but for marine or highly corrosive settings, consider 316 stainless steel jam nuts for superior corrosion resistance.
How do I install black oxide stainless steel hex jam nuts for locking?Thread the first jam nut onto the bolt, tighten it to the desired position, then thread a second nut against it. Tighten both nuts toward each other using wrenches to lock the assembly.
How do I choose the right size black oxide stainless steel hex jam nut?Select based on the bolt or screw’s thread size, such as #6-32, 1/4"-20, or 1/2"-13. Ensure the nut’s thread pitch matches the fastener. Check sizing charts or consult our team for guidance.
