Amazon has starrett punches at a decent price. I need to stake my castle nut and I’m curious if the regular center punch is good enough or do i need an automatic punch? What exactly is the difference?

Regular is just fine. 5/32

Auto punch is just spring loaded so you don't need a hammer.

And mostly is for making a center for drilling. I have a lot of tools and don't have this.

For use as a staking punch, round off the sharp tip.

The idea is to move a little metal, not put in a punch mark.

I get the indentation started with an auto punch.  Then take a 5/32 punch to the little pin hole and give it good whack with a hammer to shift over some metal into the notch.

This. A dull chisel would work to.

A Starrett 18C automatic center punch works well for me. The BCM QD endplates I like to use are pretty hard so it takes multiple strikes to get the job done, but it's easy to control the direction and depth of the staking.

I use a Starrett auto punch to start the spot, hit it three times and then follow up with a nail set punch....been working perfect this way for many years

Love my assorted punches but I don't stake my nuts.

I start out with a 1/4” center punch and finish them with a rounded off 5/16” center punch.

Nail set.  Grinder / file, etc.  Grind to a square tip. Apply hammer.



A round punch or auto punch will work, I just prefer square.

I bought a few advertised as Schmid made the other day and they have more of a rounded dish area for the staking to flow into instead of a slotted notched. Can't decide if it is better, worse, or no different if you were wanting to remove the nut.

Not sure it matters.  As long as there is material keeling the nut from rotating.

Staked nuts are the technology equivalent of wheel chocks they park under the G550 I’m wanting to get.

I’m definitely a chock wheels, pin gas blocks, and stake nuts kind of person. Not likely to have problems even if I didn’t, but I’ve NEVER had problems doing it that way. I had a surgical suture anchor punch that did the job. Wasn’t pretty but it worked. Will use a bigger punch next time, but it’s a PSA. It’s gonna get rattle canned and disrespected.

Honestly, I have used a big flat head screw driver for all of mine.

I usually double stake my castle nuts with a flat circle punch, and it comes out pretty well. That being said, I have used the ratcheted system on my last two builds, and it does make life a little easier, and it looks great too. https://www.opticsplanet.com/primary-weapons-systems-pws-ratchet-lock-sling-mount-plate.html

Go for that good stake.

Mayhew 5/32. Starrett Auto 18 A or C (forget which model I went with) and Starrett 5/32 I have all 3.

I use an automatic center punch.  They're not expensive.  Use proper tools.  Don't be a hack.

I have used one from Harbor Freight for years, and it does the trick every time.

I have a Starrett and a Harbor Freight auto punch.  The HF one hits much harder than the Starrett, but the Starrett makes a nice small precise divot.  Different uses.

I may check out a Starrett as I'm sure it is a higher quality tool. For six bucks, though, the HF one is tough to beat.

Very nice stake job, I also prefer square staking

I was trained in gunsmithing classes to use a center punch, but I use a snap punch and then follow it with a center punch. I do it that way only because I had one slip once and make a scratch.

My punches are mostly by Starrett. My 1st set were by Mayhew and they were soft, eventually most of them had to be replaced. Get quality tools to begin with, buy once, cry once.
