AS1112.1 Hex Nut
AS 1112.1 Hex Nuts are designed for general-purpose metric bolted connections where consistent dimensions, thread fit, and reliable mechanical performance are required. Their six-sided design provides convenient installation with standard tools, while the standardized metric thread allows them to be matched with compatible bolts and studs.
Our AS 1112.1 Hex Nuts can be supplied in carbon steel, alloy steel, and stainless steel, with different property classes and surface finishes available according to the application. Steel nuts can be selected for different mechanical requirements, while stainless steel options provide improved corrosion resistance for humid, outdoor, and exposed environments. Available in a range of metric sizes, these nuts are suitable for machinery, equipment, fabricated steelwork, brackets, maintenance, and general industrial assemblies. Customers can specify the thread size, pitch, material, property class, and surface treatment to match the bolt and the operating environment.

Application of AS1112 Hex Nut:
General Mechanical Fastening
AS 1112.1 Hex Nuts are widely used for bolted mechanical connections where standardized metric threads and easy tool access are required. The six-sided design allows conventional spanners and sockets to be used for efficient installation and removal.
Equipment Frames & Fabricated Components
The standardized dimensions make these nuts suitable for equipment frames, brackets, mounting plates, guards, supports, and fabricated steel components. Different nut materials and property classes can be selected to match the mechanical requirements of the complete bolted assembly.
Corrosion-Exposed Assemblies
For outdoor or humid environments, zinc-plated and hot-dip galvanized steel nuts can provide additional surface protection. Stainless steel versions, including A2 and A4 grades, are suitable where corrosion resistance is a more important consideration.
