The ASTM A563 Gr.A Hex Nuts With HDG are hot-dip galvanized fasteners designed for corrosion-resistant applications, manufactured to ASTM A563 Gr.A standards. The supplier, Ningbo S&D Metal Work Co., Ltd, offers these nuts in a size range from 1/2 to 3 inches, with the HDG coating providing enhanced protection against moisture and environmental exposure. The product is shipped from Ningbo, Zhejiang Province, China, with the supplier’s address confirmed as No.691-1, Tiantong, Dongwu.
Grade A nuts are the lowest strength class in the ASTM A563 series but are widely used for general-purpose applications where high corrosion resistance is prioritized over load-bearing capacity. The HDG coating typically adds 40-60 microns of zinc, meeting ASTM A153 standards for thickness and adhesion. Standard threading follows ASME B1.1, and the nuts are compatible with bolts of matching grade and diameter, such as A307 or SAE J429 Grade 2.
These hex nuts are commonly used in outdoor construction, utility infrastructure, and agricultural equipment where exposure to weathering is a concern. The supplier’s profile does not specify MOQ, lead time, or certifications like ISO or CE, so buyers must confirm these details directly. The HDG finish makes them suitable for applications like fence posts, highway guardrails, and telecommunications towers where longevity in harsh conditions is required.

Ningbo S&D Metal Work Co., Ltd is located at No.691-1, Tiantong, Dongwu, Ningbo, Zhejiang Province, China, with a postal code of 315000. The supplier holds a harbor trust tier, indicating a baseline verification level, but its profile does not disclose additional details such as certifications, client references, or production capacity beyond the product description.
The company’s listing highlights compliance with ASTM A563 Gr.A, B, C, and DH standards, though the specific product here is Gr.A with HDG. The profile mentions flexibility in MOQ and trade terms like FOB and CIF, but these are not quantified. Buyers should confirm the supplier’s ability to meet their order volume, lead times, and whether they provide certifications such as ISO 9001 or test reports for the HDG coating.

Before placing an order, confirm the HDG coating thickness meets ASTM A153 standards, as this directly impacts corrosion resistance. Verify that the Gr.A grade aligns with your application’s load requirements, as it is not suitable for high-strength structural connections. Request the supplier’s test reports for material composition, mechanical properties, and coating integrity to ensure compliance with your project’s specifications.
Clarify logistics details such as the port of shipment (likely Ningbo) and estimated lead time, as these are not specified in the supplier’s profile. Discuss Incoterms (e.g., FOB Ningbo or CIF to your port) and payment terms, which may include T/T or other options. For bulk orders, confirm whether the supplier can accommodate your MOQ and packaging preferences, such as palletization or custom labeling.
Conduct quality checks by measuring the HDG coating thickness using a magnetic induction gauge and verifying dimensional compliance with ASTM A563 tables. Inspect the nuts for uniform coating, absence of defects, and proper threading. For critical applications, arrange third-party inspection to validate the nuts’ mechanical properties and coating adhesion. Ensure all documentation, including MTRs, COCs, and packing lists, is provided to meet traceability and compliance requirements.
