Nylock screws

[arfmel]

Am I correct in remembering that Ruger used to tout “nylock” screws as a feature of their firearms? Do they still use them? If not, when did they quit?

I ask because if any of my Rugers have nylock screws I haven’t noticed them.

News to me. Never heard of them being used on a Ruger, or any other firearm. Quite common in industry, but not gun-making, to my knowledge. Part of their non-appeal is the relatively large thread engagement they require.

Most of my Ruger Single Actions have the NyLoc screws. Colt went to a nylon washer.

Haven't had occasion to check lately.

It was advertised in late 60’s, early 70’s using Nylok fasteners. I’ve noticed them on disassembled Rugers

I had to request new grip frame screws for a BH about 2 years ago. Don't know if the originals were nylocks (they had been loctited), but the replacements I received were.

Yet the Ruger touches were all there. An all-coil spring mechanism, frame mounted firing pin, nylock screws that wouldn't work loose

You can buy that stuff in a bottle and treat your screws once and be done with it. I don’t see it as a huge selling point.

Real nyloc nuts are a different thing altogether. I’ve never seen one in a gun.

That’s probably the time frame I’m remembering. So they’ll be in three-screw revolvers from that time frame. Thanks.

If you read the link I supplied, you'll see that Ruger's still using Nylock screws.

That link is from 2007, but that said I do know that the "nylok" screws were used on many of the later Single-Sixes and Blackhawks. Can't give an exact time frame for that, or if they are still in use.

Nylok fasteners are aerospace-grade, made to MIL-STDs. They are a penny or so more than other MIL-STD fasteners, so given Ruger's propensity for cost-cutting, it wouldn't surprise me to see them dropped in favor of cheaper options.

That said, they're A-easy to discern from non-Nylok screws, and B- used by gunsmiths who know about quality.

I say buy a box or two of various sizes. An assortment box is cheaper than a pizza. Give your arteries a break and your screws will stay put.

Yep. They were used on a commemorative revolver 12 years ago, anyway. I saw no evidence of Nylock screws in the set of grip frame replacement screws Ruger was nice enough to send me for free late last year.

Hi,

My earliest Ruger handgun was made about '82--a RH--and I don't have many since then: a BH, a GP and a MkII (all purchased new after 2000.) The GP and MkII have "owner added" blue Loc-tite on a couple of screws, but none of them has a factory Nylok (TM) style screw that I've found (I haven't removed any grip frames on guns which would have them screwed on, like the BH.) Can't speak for anyone else's guns or different time frames.
