What is a taper in a blind hole?
The taper is there to guide the tap in the hole and to slowly cut the threads in fresh material. While this is great for through-holes, where the backside of the hole is open, these only get part of the job done when you are working with a blind hole, where the hole is closed. For that, you need a bottoming tap.
What is a taper tap?
The taper tap is the most common tap design. This is the style used for creating new threaded holes.

The taper is there to guide the tap in the hole and to slowly cut the threads in fresh material.
Why do taps have tapered flutes?
The tapered flutes help ensure that the tap is centered and vertical. We ran the tap all the way through the part, so that the bottom threads were touched by the full flutes of the tap. The chips in the relief grooves of the tap are called swarf, they should be cleaned off before putting the tap away.

Sometimes using a longer nut and bolt solves the thru-hole issues that cause inserts problems, such as insert pass through.

How to stop a bolt from vibrating?
Use thread-locking material on bolts susceptible to vibration. After the thread-locking material dries, a semi-permanent bond forms, preventing the bolt from vibrating loose. When working with a blind hole application, apply the thread-locking material to the bolt's male threads. Excess thread-locker in a blind hole can stop the end of the bolt from bottoming out. In thru-hole applications, cover the hole's female threads before inserting the bolt.

When you say ‘worn out’ threads do you mean damaged or have been cross threaded. As it is not normal to have ‘worn out’ threads on a valve. Reason being I suppose is the valve thread is being operated by hand and this act does not place any wear and tare factor to the valve stem. If it is damage then it may be possible to get a triangular smooth file on the damage thread or even rethread it with the correct díe size. Other than that you could try and dress it up with a triangular smooth file. Or better still buy a new one!

How much tape is needed for a radiator?
That was the theory… In fact, “dressing” modern radiators I’ve found that as many as 22 turns of tape are necessary. You can get a feel for how much tape is necessary by assembling the first radiator connector to the first radiator boss “dry” after a while you get a feel for how much tape is necessary by the amount the fitting rattles when it’s in to the right depth, or by how far the fitting goes too deep. Fortunately, though the bosses seem oversize, the male components too small, there seems to be a consistency in batches. once you know how much tape the first one needs, you’re off, the others are likely to be the same. It’s important, because here, the radiator connection centres are 80mm greater than the nominal width of a radiator. and you can only achieve that with fittings inserted to the correct depth in bosses.
