I've got one I tried to fix yesterday to no avail. I soused it good with PB Blaster and look to try again.
I used a pipe wrench to keep the hose bib from moving but so far no good.

Put a wrench on the faucet's body to hold it in position. Then loosen the packing nut.

Generally you do not want to apply heat unless you intend on replacing all the rubber/Teflon parts as the packing is right behind the nut and will see the full heat you apply.

Siillcock

PIlot Dane,
Oops! It is not the packing but the stem nut that connect the stem to faucet body. I just want stop dripping from faucet. Packing nut is not leaking.

On close inspection I see a screw in faucet body, What the purpose of this screw?

Can you identify the bibcock so that I can get replacement kit.

Thanks.

We can not see what screw you are referring to. A picture would help. But usually there are no secondary screws holding a spigot together. There is no spindle nut on most. The packing nut does both jobs and simply unscrews (though sometimes can be difficult to break loose).

The packing and packing nut prevents water from leaking around the stem that goes to the knob when the water is turned on. A leak in the packing only occurs when the faucet is open and the water will drip where the stem enters the body of the spigot. If the washer (usually made of hard rubber) is old or damaged the faucet will drip when the sillcock is turned off.

I don't see the stem nut leaking.
It looks like it's running down the shaft and over the packing nut.

I don't see a screw. I see a red mark.
As far as a rebuild kit.... extremely doubtful. Looks pretty old.

Screw or something else?

Could screw be the locking mechanism for stem nut? Thanks

That's a manufacturers branding.

I couldn't match that branding.
You can use google image search (ebay too) to look thru old faucets.

Mueller(L) and B&K(R) were big manufacturers of that style valve.
