are these spools thread locking?

If by thread locking you mean a way to hold the thread end like the crevice on some that pinches the thread or bases that snap to hold loose end, no these spools do not. I'm happy with the thread and have used almost every color but I do have threads dangling all off of the spools.

Yes, as long as the thread size is correct. These are terrific wheel locks.

Google your brand, LST400, and see what you come up with. That is how I found my spools. If you have a model or serial number, you will get what you need by googling that.

Yes, that is the model I have. The spools do unwind when you install them. My current one had to be untangled several times before it got into a rhythm. They work so I am about to order again.

I am not sure. I would say no because this is metric threads on both ends. I hope this helps.

Use the "Removable" type of threadlocker. Somewhere on the packaging it will read, "service removable", or something similar. I used Permatex medium strength, blue threadlocker, nothing has come loose yet.

Yes they will! I've put them on my machine and my aunt's Brother Sewing Machine and work just fine. I hope you will buy the Thread and Bobbin Kit because you won't be sorry!

I just called B&D customer svc. and they said that these spools are refillable. I personally wasn't going to purchase these if they weren't but knowing this now, I can have 4 spools total that are filled and ready to go.

Yes they are. look carefully at the setting for the fill setting. Recheck after complete install. Don't over tighten attach nut

No, they are not tapped. You will either need self tapping bolts or a tap. The metal is soft and not difficult to cut threads in.

Yes they should. The "R" stands for refurbished. The spools are very simple to put in, takes about 10sec.

I haven't. It seems that there is no fitting for that thread. It is some sort of "self threading" thread. I've the nozzles threaded to an 1/8 rubber hose and they hold there ok, but with the time they will start to leak so you will have to replace the hose.

It doesn't have a start thread like plastic spools, but I didn't have any problem finding the beginning of the thread and I've used several of the spools.

Not us. You may try adding some lock-tite or some sort of thread lock compound. If that doesn't work, just replace the lock nut itself.

I have had this thread stand for 9 or so years and I have not found a spool that does not work. On strange spools or tubes of thread I have had to borrow a disk from my machine to hold them in place, but that was not a problem.

Yes, you can use various spool sizes of thread. Just make sure you use the proper size thread spool cap.
