Nuts are essential fasteners used with bolts or screws to secure components together, ensuring strength and stability in assemblies. Available in various types — such as hex nuts, lock nuts, and flange nuts — they provide reliable fastening solutions across industries. Standoffs are threaded spacers designed to create space between two components. Commonly used in electronics, PCBs, and mechanical assemblies, they provide insulation, alignment, and secure support. They come in different shapes (hex, round) and materials (brass, aluminum, steel, nylon) to suit diverse applications.
