Question: How do you install the temp guage and spigot without srtipping the threads? It doesn't go in more than 1/2 a turn
Document: I installed the ball valve and temp gauge to just  hand tight and just a 1/4 turn to snug it up after that. No Leaks. Even after long hours of heat on a gas propane burner. I will use this as my Lauder tun to hold hot water. Just built two Keggle's for mashing and boiling. But if you want a very nice &#34;all stainless steel kettle&#34; to start doing full boils, at a great price, then buy it.
Other hoop styles are much preferred.I used the kettle to brew a 5 gallon batch of beer and have these observations.- The weldless bulkhead and 1/2" ball valve are of good quality- The thermometer is good quality- The valve and thermometer are a bit too close together tad difficult to use the valve lever vertically. I had to turn it slightly for easier access.
Works great! Installation was easy, though I did have to buy more tape because the spigot leaked. I've brewed two five gallon batches since purchase with no lroblems....cheapest price I've found for a kettle, with temp and spigot fittings anywhere on the web, my lhb store, walmart, etc.
I've used this to cook 2 batches of homebrew in. You do have to put the valve and thermometer on yourself but it it not hard.NOTE:  when installing both valves, make sure that you put the nut on the correct way. One side of the nuts have a groove for the seal. If you put it on the wrong side it will leak. -1 star for no instructions on that.
Would be a great pot if it was received with all the parts. Without the bulkheads there isn't a way to install the valve and thermometer. Beware of this one, would have passed if I knew I was going to have to buy additional parts.
This is a very nice 8 gallon kettle that is all set up with thermometer and valve and ready to go for 5 gallon batches.
Brewed my first batch of beer in this kettle with zero problems. It is a really good kettle. Easy installation of spigot and thermometer, no leaks at all.
Purchased this kettle to boil sap for making maple syrup. It shaved at least 1.5 hours off from processing time!
I love the pot and am using it to brew beer.One thing to keep in mind is this is made for double batches of beer if you go that route. As the single batch will barely cover the thermometer.
constructed of the thinnest possible steel and handles, etc are barely spot welded in place. This kettle does not look like it will survive many uses of any kind. The hardware is also low quality. Valve and spigot is generic plumbing grade junk metal, not stainless.If I can find a better alternative, I'll be shipping this one back. Definitely not worth the price.
Answer: Use a plastic screw (food grade and high temp suitable - e.g. for water lines) - that is the best option I can give you. The threads seems to be non-standard.You should also try getting the correct nuts from the seller.
