Lock Nut / Thin Nut

🔩 Jam Nut / Thin Nut

(Low-Profile Hex Nut Ideal for Locking Applications and Space-Constrained Assemblies)

Neo Fasteners offers precision-manufactured Jam Nuts—also known as Thin Nuts—designed for applications requiring a low-profile locking solution. Commonly used in conjunction with a standard hex nut, the jam nut helps lock the primary nut in place, ensuring vibration resistance and maintaining preload in threaded assemblies.

🔹 Product Overview:

The Jam Nut is a thin hexagonal nut, typically about half the height of a standard hex nut. It is used by "jamming" against another nut to prevent loosening due to vibration or torque. Its compact design makes it ideal where vertical space is limited or where aesthetics demand a lower profile.
