JIS1186 High Strength Hex Nuts

JIS B 1186 Hex Nuts are designed for high-strength bolted connections in steel structures, where controlled mechanical performance and secure assembly are essential. Used together with compatible high-strength bolts and washers, these nuts form a complete fastening system for structural connections subjected to significant loads.

The nuts are available in F8 and F10 property classes, with the material and mechanical requirements controlled according to JIS B 1186. Different sizes and surface finishes can be supplied to suit structural connection requirements, including options for outdoor steelwork where additional corrosion protection is required. JIS B 1186 Hex Nuts are commonly used in steel buildings, bridges, transmission structures, industrial steelwork, and other heavy-duty structural assemblies. For proper selection, the nut grade should be matched with the corresponding bolt and washer set, while thread size, surface treatment, and connection requirements should be considered together.

Specification:

JIS B 1186 Hex Nuts are manufactured for high-strength structural bolting assemblies and are specified by their nut property class, dimensions, thread requirements, and mechanical properties. F8 and F10 nuts are available for use with compatible high-strength bolts and washers according to the required connection specification. The nuts can be supplied in suitable steel materials and surface finishes for different structural environments. Plain, zinc-plated, and hot-dip galvanized finishes can be provided according to project requirements.

Dimension Chart of JIS1186 Hex Nuts:

The dimension chart provides the key measurements required to select JIS B 1186 Hex Nuts for high-strength structural connections. Nominal diameter, nut height, width across flats, and thread pitch should be matched with the corresponding bolt and washer set to ensure proper fit and assembly.
