ASTM A194 2H Heavy Hex Nuts GR5 Carbon Steel UNC Fastener Nuts

These ASTM A194 2H heavy hex nuts are designed for strong threaded fastening applications where a durable nut body and stable connection are required. The product title identifies the nut as an ASTM A194 2H heavy nut, GR5 hex nut, and UNC fastener nut, making it suitable for projects that require heavy-duty nut performance and compatibility with matching bolts or threaded rods.

The product page displays material options of 316 stainless steel, stainless steel, and steel, and the detailed attribute table lists carbon steel as the material. This gives buyers several material directions depending on the application environment. Carbon steel is widely used for industrial fastening due to its strength and cost efficiency. Stainless steel and 316 stainless steel options are suitable when improved corrosion resistance is required.

Surface treatment options include blackening, zinc plated, and yellow zinc chromate. Blackening provides a dark surface finish and is often selected for appearance or controlled indoor-use requirements. Zinc plating and yellow zinc chromate help improve surface protection and are commonly used for general industrial fasteners.

The product model is listed as M2-M10, with displayed thread sizes including M2, M2.9, M6, M10, M20, and M27. The measurement system is shown as metric, while the product name also includes UNC, so size and thread type should be confirmed before production according to the buyer’s drawing, sample, or order specification.

Material and Grade Description

This product page identifies the fastener as an ASTM A194 2H heavy nut and GR5 hex nut. ASTM A194 2H is commonly associated with heavy-duty nut applications, and the page uses this designation directly in the product name. GR5 is also shown in the title, so it should be included clearly in the product specification and quotation communication.

For materials, the selectable material area shows 316 stainless steel, stainless steel, and steel. The detailed attributes list carbon steel as the material. Therefore, the product can be described as a steel / carbon steel heavy hex nut with stainless steel material options available, depending on project requirements.

Carbon steel is suitable for general heavy-duty fastening, equipment assembly, industrial maintenance, and structural hardware where strength and economical supply are important.

Steel is suitable for standard fastening requirements and can be matched with different coatings or finishes.

Stainless steel provides better corrosion resistance for humid, exposed, or cleaner environments.

316 stainless steel offers stronger corrosion resistance than general stainless steel and is suitable for more demanding environments where rust resistance is important.

Available finishes include blackening, zinc plated, and yellow zinc chromate, allowing buyers to choose according to corrosion protection, appearance, and assembly environment.
