The product is a heavy hex structural nut conforming to ASTM A194 2H with a Teflon coating. It features a hexagon head that provides a secure grip during installation. The nut is manufactured from carbon steel and receives a heat‑treated finish to increase strength. It complies with the ASTM A194 2H standard for dimensional and mechanical requirements.
Carbon steel of grade 40 is typical for this class of fasteners, offering a good balance of strength and machinability. Standard heat treatment for ASTM A194 2H nuts is quench and temper, delivering a typical tensile strength of 1250 MPa. A PTFE (Teflon) coating of typical thickness 0.1 mm reduces friction and adds corrosion resistance in harsh environments. Typical size range for heavy hex nuts spans from M12 to M48, matching the dimensions used in structural steel assemblies.
These nuts are widely used in heavy machinery, bridge construction and large‑scale steel structures where reliable fastening is essential. OEMs, construction contractors and equipment manufacturers are the primary buyers. The supplier offers flexible minimum order quantities and ships under FOB or CIF terms. Payment can be made by telegraphic transfer or letter of credit, and packaging is designed to protect the nuts during transit.

Before placing an order, verify that the nuts meet the required ASTM A194 2H specifications by requesting the mill test certificate and checking the Teflon coating thickness. Confirm the carbon‑steel grade and heat‑treatment process to ensure compatibility with your design strength. Ask the supplier to provide dimensional drawings for the specific size you need, and review any available compliance documentation.
Discuss logistics early, confirming whether you prefer FOB or CIF shipping and the port of loading in China. Inquire about the typical lead time for production and packaging, and negotiate payment terms such as a letter of credit or telegraphic transfer. Clarify the incoterm responsibilities for freight, insurance and customs duties to avoid unexpected costs.
Arrange a third‑party inspection before shipment to verify coating integrity, dimensional accuracy and mechanical properties. Request a pre‑shipment report that includes the test results for tensile strength and coating adhesion. Ensure the packing list and certificate of origin are included in the documentation package for smooth customs clearance.
