Stainless Steel SS 304 Checknut, Size: 1"", Packaging Type: Plastic Packet

An SS 304 Checknut (also known as a jam nut, lock nut, or thin nut) is a low-profile hexagonal nut used to "check" or lock another nut in place, preventing it from loosening due to vibration or rotation. Because it is thinner than a standard hex nut, it is ideal for tight spaces or as a secondary locking mechanism on threaded rods and bolts.
