DIN 934 Zinc Plated Black Metric Hex Nuts for Industrial Fastening

DIN 934 hex nuts are standard metric fastening nuts used together with bolts, studs, threaded rods, screws, and washers. The six‑sided design allows easy tightening with common hand tools or assembly equipment, making them suitable for both manual installation and bulk industrial use.

Hotop Fasteners supplies these hex nuts in multiple material options, including carbon steel, stainless steel, steel, alloy, and brass. Carbon steel is suitable for general industrial fastening and high‑volume hardware supply, while stainless steel can be selected for applications requiring better corrosion resistance. Alloy and brass options are available for special fastening requirements.

Surface treatment options include zinc plated, black, galvanized, passivated, yellow zinc chromate, plain, and HDG. Buyers can select the finish according to the application environment, required appearance, and corrosion protection needs. Common metric sizes include M6, M8, M10, M12, M14, M16, M18, M20, and M22, with additional sizes available according to customer requirements.

Key Specifications

Material and Finish Selection

For standard industrial fastening, carbon steel hex nuts are a practical choice for strength, cost control, and large‑volume use. For environments where rust resistance or a cleaner appearance is required, stainless steel hex nuts can be selected. Alloy and brass options are suitable for projects with specific material requirements.

For surface treatment, zinc plated and galvanized finishes are commonly used for general corrosion protection. Black finish is suitable for dark hardware assemblies and black fastener systems. Yellow zinc chromate provides a yellow‑gold appearance, while HDG is suitable for applications requiring stronger surface protection in outdoor or demanding environments.
