ASTM A194 GR.2H heavy hex nuts from Ningbo High Tensile Bolts Ltd. are carbon steel fasteners designed for high-pressure and high-temperature applications, compliant with ASTM A194 standards. The nuts are available in sizes ranging from M6 to M100 and 1/4 to 4 inches, with custom sizing offered upon request. Finish options include zinc plating in yellow, white, blue, or black, hot dip galvanized, black oxide, Geomet, Dacromet, anodization, nickel plating, zinc-nickel plating, and PTFE coatings for enhanced corrosion resistance.
The Grade 2H designation specifies a heat-treated carbon steel construction with a typical hardness of 22-32 HRC and a proof load exceeding 235 MPa, suitable for pairing with A193 Grade B7 bolts. Standard industry tolerances for heavy hex nuts apply, with a typical thread engagement of 1.5 times the nominal diameter and a standard hex width of 1.5 to 1.75 times the nominal size. These nuts are commonly used in flanged joints, pressure vessels, and structural applications where vibration resistance and durability are critical.
Industrial buyers in oil and gas, petrochemical, and power generation sectors source these nuts for critical bolting assemblies. Ningbo High Tensile Bolts Ltd. supplies them in bulk with flexible packaging options, including cartons, wooden cases, or pallets. Trade terms such as MOQ, incoterms, and lead times are confirmed per inquiry, as the supplier tailors logistics to project requirements.

Before ordering, verify the exact grade and material composition to ensure compatibility with your bolting assembly. Request certificates of compliance for ASTM A194 GR.2H, including heat treatment records and mechanical test reports. Confirm that the finish meets the environmental conditions of your application, such as corrosion resistance for outdoor or marine use.
Logistics details to confirm include the port of shipment (typically Ningbo or Shanghai), incoterms (e.g., FOB, CIF), and packaging preferences. The supplier offers bulk packaging in cartons, wooden cases, or pallets, but lead times and MOQs vary by order size and specifications. Always clarify these terms in writing to avoid delays.
Quality checks should include visual inspection for surface defects, dimensional verification using calipers or thread gauges, and hardness testing if required. For coated nuts, verify coating thickness and uniformity using a micrometer or magnetic induction gauge. Request a pre-shipment inspection report to ensure all specifications are met before finalizing payment.
