Why Choose Zinc Plated Steel Hex Jam Nuts?
Our zinc plated steel hex jam nuts at AlbanyCountyFasteners.com, also known as zinc 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 Grade 2 low carbon steel with a zinc plating, offering moderate corrosion resistance for indoor or sheltered environments. 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, ASTM F1941, IFI tolerances, REACH, and RoHS standards and are ideal for automotive, machinery, and construction projects requiring cost-effective, reliable locking.
- Moderate Corrosion Resistance: Zinc plating protects against rust in dry or indoor settings.
- Low Profile: Thinner design fits tight spaces where standard nuts won’t.
- Cost-Effective: Affordable solution for high-volume projects.
- High Standards: Compliant with ASME B18.2.2 and ASTM F1941 for reliability.
Applications for Zinc Plated Steel Hex Jam Nuts
Zinc jam nuts are designed for projects requiring a low-profile, corrosion-resistant locking solution with bolts or screws to secure assemblies or fit tight spaces. Their versatility makes them suitable for:
- Automotive and machinery adjustments
- Indoor construction and structural assemblies
- Electrical and plumbing fixtures
- General industrial equipment
Frequently Asked Questions (FAQ)
Zinc plated steel hex jam nuts are low-profile, hexagonal nuts made from Grade 2 low carbon steel with a zinc coating, used as locknuts by tightening against another nut or in tight spaces, offering moderate corrosion resistance.
How do zinc plated steel hex jam nuts differ from DIN 439B zinc plated steel metric hex jam nuts?Zinc plated steel hex jam nuts use imperial sizing for U.S.-based applications, while DIN 439B zinc plated steel metric hex jam nuts use metric sizing for international standards.
Are zinc plated steel hex jam nuts suitable for outdoor use?They provide moderate corrosion resistance for dry or sheltered outdoor settings, but for marine or highly corrosive environments, consider 316 stainless steel or silicon bronze jam nuts for better durability.
How do I install zinc plated 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 zinc plated 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.
