MS17830-08C | صواميل ذاتية القفل عسكرية المواصفات (100/عبوة)

Finally got around to using these on my motorcycle build and the self-locking feature held everything tight through a rough test ride. Each nut has that distinct nylon insert that really does grip the threads without damaging them.

Second batch I've ordered, and the locking collar holds steady even on my trailer hitch bolts that rattle loose every season. Each nut seats cleanly without galling the threads, so I'm not fighting with replacements halfway through a job.

The locking collar bites down firm enough that I don't worry about anything rattling loose on my workbench setups anymore. A hundred in the pack means I've got plenty spares for future projects, and they thread on smoothly without any awkward binding.
