smallest locking biner?

I asked about the largest non-locking biner last week.  Now I'm curious about the smallest locker.  I usually carry a couple smaller (BD positrons) lockers for bolted anchors because sometimes the hangers don't let the bigger guys in due to rock face features.  Is there a locker even smaller? any ideas what the SMALLEST locker is?

(ORIGINAL MESSAGE):  I've been using the OP five-o biner for my nuts.  its quite big but is not a key lock.  of course its never an issue until I have to put a nut in under strain, then of course the wire finds its way right into the nose.  Its tough to tell online the size of the biner and am hoping for some guidance.

DMM makes one, so does CAMP  Google: "CAMP USA Oval XL Non-Locking Carabiner"  I found a lot of places selling it.

The CAMP Photon is pretty damn small. Useless if you want to clove hitch the rope. Your positron should work fine, why buy more useless junk. I use my Photons to hold my shoes and water bottles.

Trango superfly are pretty small. That's what I've been using. 

While not a conventional locker, these Edelrid Slide carabiners are small and super useful. I like them.

I've found weighmyrack.com to be a great tool for comparing carabiners. Not just weight but they also list gate opening and stuff like that. 

DMM Perfecto are pretty good to store buts. I don't know if they are the smallest carabiner, but probably the smallest locking oval one.

yeah but they don't list size. (length specifically). 

CAMP Photon Locker is probably the LIGHTEST locker. This Mammut is pretty small, too.

DMM Phantom screwgate is the smallest and lightest locker I own. Same weight as Photon locker so not really sure which is smaller, but it’s a great biner and I highly recommend.

I've been carrying a few Grivel Plume lockers lately. They're the lightest locker out there per WeighMyRack, 37g. When I received them I thought they looked like toys or keychain biners but after a bunch of multipitch outings I really like them. They're perfect for anchors, big enough to clove a 9.5 through, the gate opening is much larger than the size of the biner suggests, and they fit through the smallest chains if you can't/don't want to go in the hanger.
They pop up randomly on US sites once in a while...

This.  I hang my guide device from them since they're kinda pricey.  I've got two wish I had more!

Probably not the smallest, but the Petzl S'MD is awesome and comes in twist lock too. Might be the smallest twist lock if that counts for anything.

Have you ever heard of anyone carrying a 120cm sling and two lockers? This way you can extend gear with double length runner and not worry about the rope coming unclipped if you fall. That’s what I use my small biners for. Well that’s not true. I’m a gear dork because I’m fat and don’t climb hard. I have different carabiners for different jobs. Keeps me from having to think what I forgot. I have a Camp Photon for my autoblock,

Oh yea heard if it for clipping in but not for racking nuts or cams. I probably read it wrong. Sounded like he wants a locker to rack his nuts on.

Edit: fabios response confused I

 Now I’m confused too. At least the OP will be safe? Now I wanna go out to a popular multi pitch this weekend and use only lockers on everything! IG the looks people give me as they pass
