Why Our ASME B18.2.2 Nuts Stand Out？

1. Precision Manufacturing

Every nut undergoes strict quality checks to meet ASME B18.2.2 tolerances (±0.001"), ensuring seamless compatibility with matching bolts.

2. Material Versatility

Choose from carbon steel for high-strength needs or stainless steel (Grade 316/304) for corrosion resistance in marine or chemical environments.

3. Global Compliance

Our nuts adhere to ASME, DIN, and GB standards, simplifying procurement for multinational projects.

4. Ready-to-Ship Inventory

With over 10 million units in stock, we reduce lead times to 1–2 weeks for bulk orders.

5. Tailored Solutions

Need slotted nuts for cotter pins or thick nuts for extra load distribution? Our R&D team can customize designs without compromising ASME compliance.

Applications Across Industries

Construction: Securing structural beams and heavy equipment.
Oil & Gas: Withstanding high-pressure valve assemblies.
Renewable Energy: Bolting wind turbine components.
Automotive: Engine part fastening with vibration resistance.

Built to Endure Extreme Conditions

Our ASME B18.2.2 Nuts excel in environments where failure isn’t an option. The zinc-plated variants offer 500+ hours of salt-spray resistance, while hot-dip galvanized coatings protect against harsh weather. For high-temperature settings, ASTM A194 Grade 8M nuts maintain integrity up to 300°C.

Quality Assurance You Can Trust

Batch Testing: 100% dimensional checks and torque resistance validation.
Certifications: ISO 9001, IATF 16949, and ASTM material traceability.
Packaging: ISTA-3A certified crates prevent corrosion during transit.
