AN316 Thin Jam Nut (Non-Locking Check Nut)
These plated steel nuts are Military Specification* versions of non-locking jam nuts. These nuts are typically used to lock in adjustments where a male threaded part screws only partway into a female threaded part (rod ends, grub screws, bulkhead fittings, etc). These jam nuts are thinner than the AN315 specification** for use in tighter installations. Sold individually.
* Except Part No. AN316-10-L. This is a very high-quality cad-plated steel jam nut, but it has a smaller hex and is thicker than the AN316 standard.
** Except Part No. AN316-3-R and -L. The AN316 standard does not include the 10-32 size, so this size conforms to the thicker AN315 standard.
