Brand:‎PRIME-LINE

Lock nuts (or locknuts) feature a nylon insert that grips onto threads and resists loosening due to vibration. It is best to only use each nut once as its holding power is reduced if reused. They should not be used in extremely high heat or in certain chemical environments as that could weaken the plastic insert.

Thread Type: Coarse, Thread Class: UNC-2B. The side with the nylon insert should face towards the tip of the bolt, not towards the surface being fastened. Can also be used as a secondary nut to help lock the main nut in place. Great for use in applications where the bolt may be subject to vibration. Features an internal nylon ring that grips bolt threads better than a standard finished nut. Size: 1/4 inch-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.
