Self-Threading Lock Nuts

Self-threading lock nuts are designed to form their own locking threads upon installation. Crafted from malleable materials such as nylon, they adapt to the male fastener's threads for a secure fit. These nuts offer superior resistance to loosening compared to nylon insert lock nuts, though they are not as robust as those equipped with washers.

Nylon Insert Lock Nuts

Designed for applications prone to vibration, nylon insert lock nuts feature a deformable nylon ring that grips the bolt threads to prevent loosening. While reusable, they are not suitable for high-temperature environments and represent the least robust option among lock nuts.

Available in reversible designs with central locking threads or one-directional versions with offset locking sections, these nuts offer superior resistance to rotation compared to serrated lock nuts. Ideal for high-temperature environments where nylon locking mechanisms fail.
