Nylock Jam Nuts are low-profile hexagonal lock nuts that feature a nylon insert designed to prevent loosening caused by vibration or rotation. Commonly referred to as nylon insert lock nuts, thin nylock nuts, nylon hex jam nuts, or thin nylon stop nuts, these fasteners are ideal for applications requiring secure fastening in limited spaces. However, they are not recommended for use in high-temperature environments due to the nylon component’s heat sensitivity.

These nuts are manufactured in both metric and imperial standards, and are compatible with various thread types including UNC (Unified National Coarse), UNF (Unified National Fine), UN (Unified Fixed Pitch), and ISO metric threads. They are available across a broad spectrum of materials and ASTM specifications, such as stainless steel, carbon steel, and specialized alloys.
