The ASTM A563 GC/DH Heavy Hex Structural Nut is a carbon steel or alloy steel fastener designed for high-strength structural applications, conforming to ASTM A563 standards. This listing specifies plain, zinc, or black oxide finishes with material options in stainless steel, carbon steel, or alloy steel. Packaged in cartons or plastic bags on pallets, the product is supplied from Ningbo, China, with a monthly capacity of 100,000 pieces and port options via Shanghai or Ningbo.
Heavy hex structural nuts in GC and DH grades are engineered for use with high-strength bolts in construction, heavy machinery, and infrastructure projects. The GC grade is typically used for general applications, while DH is heat-treated for higher proof loads, often paired with A325 or A490 bolts. Standard industry practice includes threading per ASME B1.1 and dimensional tolerances to ASTM A563, with typical hardness values of 120-250 HB for carbon steel variants.
Primary buyers include steel fabricators, bridge contractors, and equipment manufacturers sourcing for structural connections. Trade terms include T/T payment with supply ability scaled to bulk orders. The nuts are compatible with standard heavy hex bolt heads and are used in applications like structural steel frameworks, industrial equipment assembly, and transportation infrastructure where vibration resistance and load-bearing capacity are critical.

Before ordering, verify the grade (GC or DH) and confirm it matches your bolt specifications, as DH is required for high-strength applications like A325 bolts. Request the supplier’s Mill Test Report (MTR) to check material composition and mechanical properties, including hardness and proof load. Ensure the finish (plain, zinc, or black oxide) aligns with your corrosion resistance needs and environmental conditions.
Confirm logistics details such as port of shipment (Shanghai or Ningbo) and lead time, as the supplier’s profile does not specify these. Clarify Incoterms (e.g., FOB Ningbo) and payment terms, which are currently listed as T/T only. For bulk orders, discuss packaging requirements to ensure compatibility with your handling equipment and export regulations.
Quality checks should include dimensional verification against ASTM A563 tables for head width, height, and thread pitch. Conduct a visual inspection for finish consistency and defects. For critical applications, arrange third-party inspection to validate mechanical properties and surface treatment thickness. Request documentation such as MTRs, COCs, and packing lists to ensure traceability and compliance with your project’s standards.
