The Heavy Hex Structural Nut A194 2HM is designed for robust fastening in demanding industrial assemblies, meeting ASTM A194 Grade 2HM specifications and available in sizes from ½ inch to 4 inch. Its heavy‑hex shape distributes load evenly, and it can be supplied with black, zinc‑plated or yellow‑zinc surface treatments to suit different corrosion environments. Flexible minimum order quantities are supported and shipping can be arranged on FOB or CIF basis.
The nuts are forged from medium‑carbon alloy steel that is quenched and tempered to achieve typical hardness of 30‑35 HRC and tensile strength of at least 120 ksi, matching the A194 2HM standard. Standard industry practice includes a Unified National Coarse (UNC) thread profile that aligns with the corresponding bolt sizes. The various surface treatments provide corrosion resistance levels from moderate (black oxide) to high (zinc plating).
They are commonly installed in steel structures, bridge components and heavy‑equipment sub‑assemblies where secure, vibration‑resistant joints are required. Construction contractors, equipment manufacturers and automotive suppliers often specify these nuts for critical connections. Prospective buyers should verify the required size, coating and any certification documentation before placing the order.

Prior to ordering, confirm that the nuts meet ASTM A194 Grade 2HM and that the chosen surface treatment matches the environmental conditions of your project. Request the mill test certificate and, if applicable, a coating thickness report for the selected finish. Verify that the supplied size range and thread profile are compatible with the bolts you intend to use.
Discuss the preferred Incoterm with the supplier, whether FOB Ningbo Port or CIF to your destination, and obtain an estimated production lead time, which typically ranges from four to six weeks for standard quantities. Clarify payment arrangements such as telegraphic transfer, letter of credit or other terms that suit your financial controls. Ensure that any freight forwarder requirements are communicated early to avoid delays.
Plan for a third‑party inspection either at the factory or upon arrival to validate dimensions, hardness and coating integrity. Ask for a visual inspection report, hardness test results and, if needed, a corrosion resistance test for the selected surface treatment. Confirm that the commercial invoice, packing list and certificate of origin are included in the shipping documents to streamline customs clearance in the importing country.
