Hex Nuts are six-sided fasteners that mate with externally threaded bolts or screws to clamp components together. Their standard hexagonal shape makes them easy to grip with spanners or wrenches, while their compact size provides strong and reliable fastening for a variety of assemblies. Available in multiple grades, sizes, and finishes, hex nuts can be used in low-load domestic applications as well as demanding industrial environments. They are often used with washers to improve load distribution and prevent loosening under vibration.
