A hex nut, short for hexagonal nut, is a type of fastener with a six-sided shape (hexagon) and internal, or female, threads that mate with the male threads of a bolt or screw. The primary purpose of a hex nut is to secure and fasten the bolt or screw in place. Key features of a hex nut are Hexagonal Shape, Internal Threads, Flange.
Hex nuts are widely used in various applications across industries, including automotive, construction, machinery, electronics, and more. They come in a range of sizes, materials, and grades, each suited for specific applications based on factors such as load capacity, environmental conditions, and corrosion resistance.
Hex nuts can be graded based on their strength and performance. Common grades include Grade 2,
Grade 5, and Grade 8 for steel nuts, with Grade 8 being the strongest.
The size of a hex nut is specified by its diameter and thread pitch,
which should match the corresponding bolt or screw.
Common materials for hex nuts include steel, stainless steel, brass, aluminum, and more.
