Import Astm A194 2h Heavy Hex Nuts — Buy in Bulk from Supplier in China

Ningbo Beilun Milfast Metalworks Co., Ltd. supplies ASTM A194 2H heavy hex nuts in sizes ranging from 1/4" to 4". These nuts are manufactured from carbon steel, alloy steel, or stainless steel, with surface finishes including plain, black, zinc-plated (ZP), yellow zinc-plated (YZP), hot-dip galvanized (HDG), dacromet, nickel-plating, and brass-plating. The ASTM A194 standard ensures these nuts meet the mechanical properties required for high-pressure and high-temperature applications.

The heavy hex design provides a larger bearing surface, reducing the risk of galling or deformation under high torque. Typical industry specifications for these nuts include a thread pitch per ASME B1.1 and a width across flats that adheres to ASME B18.2.2. Stainless steel variants, such as A194 Gr. 8 or 8M, are often selected for corrosive environments, while carbon steel grades like 2H are standard for general industrial use.

These nuts are commonly used in flanged connections for pipelines, valves, and pressure vessels in sectors like oil and gas, chemical processing, and power generation. Ningbo Beilun Milfast Metalworks packages the nuts in 25 kg boxes, with 36 boxes per pallet, facilitating efficient bulk handling. Buyers should confirm the exact grade, size, and finish availability, as well as any additional certifications or testing requirements.

Ningbo Beilun Milfast Metalworks Co., Ltd. is located in Qijiashan Street, Lianhe Area, Beilun, Ningbo, Zhejiang, China. The supplier specializes in fasteners, including heavy hex nuts under ASTM A194, and serves international markets with a focus on industrial and construction sectors.
