ANSI/ASME B18.2.1 Hexagon Head Bolt, black oxide flange bolts, custom automotive fasteners
The ANSI/ASME B18.2.1 Hexagon Head Bolt from Zhejiang Zhongrui Auto Parts Co., Ltd. is a carbon steel fastener with a black oxide coating, designed for high-stress automotive and industrial applications. The flange under the hex head spreads the clamping load, reducing the risk of surface damage or stripping during installation. Each bolt conforms to ANSI/ASME B18.2.1 dimensional standards, ensuring compatibility with standard tooling and mating components in North American markets.
Manufactured from high-grade carbon steel, these bolts offer typical tensile strengths in the 400 to 600 MPa range for standard Grade 5 equivalents, with the black oxide finish providing moderate corrosion resistance suitable for indoor or dry environments. The flange diameter is standard at 1.5 times the nominal bolt diameter, and thread tolerances meet typical 6g industry norms. These fasteners are commonly supplied in M6 to M20 metric sizes or 1/4 to 3/4 inch UNC/UNF threads, with lengths from 20 mm to 150 mm as per project specifications.
Primarily used in engine assemblies, chassis frameworks and suspension systems for light and heavy-duty vehicles, these bolts are also adopted in machinery manufacturing where vibration resistance and load distribution are critical. Buyers typically source them in bulk with MOQs aligned to automotive production runs. Packaging is industrial-grade, often in sealed plastic bags or wooden crates to prevent transit damage. Confirm Incoterms such as FOB Ningbo or CIF destination port, and verify if ISO 9001 or SGS test reports are available for the batch.

Sourcing ANSI/ASME B18.2.1 Hexagon Head Bolt from Zhejiang Zhongrui Auto Parts Co., Ltd. - China Import Guide
Before ordering, verify the supplier's compliance with ANSI/ASME B18.2.1 by requesting dimensional inspection reports and material certificates for the specific batch. Confirm that the black oxide coating meets your environmental exposure requirements, as it may not suffice for high-corrosion applications. Check if the bolts are manufactured in-house or sourced from a third party to assess quality consistency.
For logistics, confirm the nearest export port (typically Ningbo or Shanghai for Zhejiang-based suppliers) and negotiate Incoterms such as FOB or CIF based on your control preferences for freight and insurance. Clarify packaging standards, especially for bulk orders, and ensure the supplier can provide export-ready documentation, including packing lists and commercial invoices with HS codes for customs clearance.
Quality checks should include visual inspection for coating uniformity, thread integrity, and flange dimensions. Request a sample lot for destructive testing if the application is critical, such as tensile or torque tests to validate performance. Ensure the supplier can provide a test report for each production batch, including material composition and mechanical properties, to meet your internal quality standards.
