Thin nuts, also known as jam nuts or low-profile hex nuts, are essential space-saving fasteners designed for applications where standard nuts are too tall. With a height that’s 30–50% shorter than regular hex nuts, they excel in tight environments such as dual-nut locking systems, electronics, automotive assemblies, and machinery. Their compact design doesn’t compromise on strength, making them ideal for securing joints in high-vibration or confined spaces.
