Perfect in every way
I paired these lightweight castle nuts up with some Timber Creek QD aluminum endplates. Plain steel PSA nut and plate = 1.18oz. PSA lightweight aluminum (fluted) castle nut and TC plate = 0.48oz! Besides being a whole 0.7 ounces lighter, it looks great and the glossy black anodized finish was flawless. The threads are well-cut and well-finished.

It should be noted there are all kinds of weird rotating and non-rotating QD endplates and castle nuts and buffer tube retaining devices on the market. The non-rotating Timber Creek aluminum endplate offers 45 or 90 degree positions for connecting Grovtec QD slings (perfect fit, same company) that won't scratch up your nice castle nut and buffer tube.

I cleaned the threads on the nuts and buffer tubes and used plastic film to keep from scratching the nuts with the spanner wrench. The nuts snugged up nicely with an estimated 25 ft lbs of torque and I don't see them coming loose or wearing out if they need to be re-torqued a few times. That's a PSA fluted buffer tube which also saves you roughly 0.3 ounces over most 6 position tubes and it looks fantastic too! These nuts are a bargain for retaining your favorite end plate and buffer tube!
Looks great, works great. That's a FAB folding grip, Strike CH, Franklin Binary w/ PSA antiwalk pins
