Brand:‎PRIME-LINE

3/5

Les contre-écrous (ou contre-écrous) comportent un insert en nylon qui adhère aux filetages et résiste au desserrage dû aux vibrations. Il est préférable de n'utiliser chaque écrou qu'une seule fois car son pouvoir de maintien est réduit s'il est réutilisé. Ils ne doivent pas être utilisés à des températures extrêmement élevées ou dans certains environnements chimiques car cela pourrait affaiblir l'insert en plastique.

Type de filetage : grossier, classe de filetage : UNC-2B. Le côté avec l'insert en nylon doit être orienté vers la pointe du boulon, et non vers la surface à fixer. Peut également être utilisé comme écrou secondaire pour aider à verrouiller l'écrou principal en place. Idéal pour une utilisation dans les applications où le boulon peut être soumis à des vibrations. Dispose d'un anneau interne en nylon qui saisit mieux les filetages des boulons qu'un écrou fini standard. Taille : 1/4 pouce-20.

As advertised...
As advertised, no complaints. Fit and finish is super, but for this price who really is complaining?

Had to cut bolts and buy different nuts
Another review mentioned quality issues and galling. I can confirm this to be the case on THREE separate bolts. I had to drill the head out of one bolt and cut two others. I got another 1/4-20 nut locally and they performed just fine. I did receive a refund, and the satisfaction of leaving a one star review- so thanks Amazon. 3 bucks for 50 bucks worth of time.

Good Quality
These are good quality lock nuts. Similar to other lock nuts I have purchased at West Marine for over twice the price for this size.

crap
the nylon washer in the end of the nut is too small. it does not allow room for the bold to go through, I twisted one bold off trying to get it tight and had to cut another one off because i couldn't back out the bolt

Jambs
The nylon jams on any bolt put into this nut. The bolt can not be removed or completely tightened. I have broken two bolts just trying to remove the nut.
