HornadySure-Loc Lock Rings, 6 Pack, 044606 - Fits on Standard 7/8-14 Inch Threaded Dies & Accessories - Split Ring Design Die Lock Rings Applies Constant Pressure & Wrench Flats for Easy On/Off

Worked great for my Hornady reloader. The dues I was using did not come with the split rings. Replaced them with these.

Hornady cross lock die rings are the best. Easy to adjust and once tightened stay securely in position. Much better than the RCBS lock rings that tend to deform the die threads when you tighten the brass set screw that directly secures on the threads and extremely better than the Lee lock rings that never stay put, plus the Hornady lock rings you can adjust with an open end wrench. I recommend them. Been handloading for decades and they are all I use now. Shipping was fast as well.

Very consistent quality. Good value for the money.

These lock rings are simply brilliant and brilliantly simple. To think: I used to tighten down tiny brass inserts in factory lock rings absolutely KNOWING they weren’t going to stay and hold. I guess that’s the definition of stupidity, though: doing the same thing over and over again and expecting different results. That’s how I learned to set up dies, though, so why change what “works?”Enter the Hornady Sure-LOC Lock Rings. Someone thought to themselves, “How about instead of hoping a minuscule brass insert will magically hold a lock ring in place, we physically tighten the ENTIRE lock ring around the die body to increase both the force of the hold and the surface area upon which the hold is applied?” It really is that simply genius.I use these on all of my precision dies and even my non-precision seating dies. They just make life easier. When the lock nut’s properly tightened, the ring will absolutely REFUSE to budge. If it somehow DOES budge, that means the laws of physics no longer apply, so you might wanna grab onto something and hold on...Pro Tips:1.) Be sure to pick up a compatible wrench, because cool new stuff isn’t as cool without the tools to use it.2.) When installing a Hornady Sure-LOCK ring on a die for the first time, be sure not to ENTIRELY tighten the lock ring nut right off the bat. If you do, you’ll need industrial-grade hardware to remove your die from your press. Instead, seat your die to the appropriate depth, spin the lock ring down (counterclockwise) until it JUST BARELY touches the top of your press, and barely tighten the lock nut in place. Then, VERY CAREFULLY, rotate both the die and lock ring counterclockwise ½ to ¾ turn - making sure they’re still perfectly aligned in relation to one another, but the lock ring is no longer in contact with the top of your press - and then hoss that lock nut down for good.3.) Don’t overzealously tighten the lock nut, because you WILL strip the corners out of its Allen/hex head.

Like how they clamp.

I'm exchanging the lock nuts on reloading dies that have brass set screws as the screws damage the die threads. Theses lock nuts have a gap with a threaded cap screw that tightens to secure its position to the die. The flat sides allow a crescent wrench, or similar, a sure grip to tighten without damage. No brainer!

If they were slightly less outside diameter they would be perfect
