Nuts, or mating fasteners, are available in hundreds of different shapes and sizes for any project or application. Varieties are normally hexagonal or square in shape and have either coarse or fine internal threads that correspond to those of a mating bolt.
**Hex Nuts** are the most commonly used nuts, suitable for fastening most machinery and equipment. They offer economical strength for standard bolting applications with straightforward assembly and reliable performance.
**Lock Nuts** prevent loosening from vibration and movement, critical in machinery, automotive applications, and equipment where fastener security is essential. K2 stocks nylon-insert lock nuts for moderate temperatures and all-metal designs for high-heat environments.
**Material Options**. K2 offers a wide range of material selection.
