Thanks! Another newbe question - this sounds stupid but when I eventually take the lid aluminum end caps off to de-grease and repaint, how do I remove the bolts if the heads of the bolts are round. I understand the inside nuts are hex but what do I use at the other end to hold the bolt while I take the nut off?
Hey Val, welcome to the community...
I just did this on my first Weber renovation — a 1996 Spirit 500.
I learned much of what I am about to share from the experts on this forum. This info is not original to me, but I have found that it works:
The original bolts on my grill were smooth flat heads with splines to give them some grab inside the aluminum endcaps. They were secured by self-thread cutting nuts (I believe 7/16" -- like most bolts you'll encounter on these amazing grills. About half of mine came out by just putting a socket on my impact driver (yep, overkill... you can use a ratchet) and lefty-loosey they came off very easily. The others started to release and then the flat head started spinning. Here's what I did to get them off...
Spray some penetrant on the threads, let it sit for a while. While it is penetrating, go find a skinny blade flat screwdriver. Push the bolt out from the nut side using your hand. Slide the screwdriver in the thin gap that now exists between the bolt head and the endcap. Put some pressure on the screwdriver to pull the bolt, bringing the nut up against the endcap. Now put the socket back on the nut while continuing to hold pressure on the bolt. I like using a drill or driver since it works quickly and your hands are already busy on separate tasks.
If it doesn't work, pull out the skinny screwdriver and grab a bigger one. Now put that between the nut and the endcap. Turn or lift it to put pressure on the nut allowing the splines on the bolt to grab. Again, use the 7/16" socket and drill/driver to spin the nut off.
This worked for me. I guess if it doesn't work for you, I'd get a dremel with cut-off disc and zip off the nut and then tap the bolt out.
Either way, replace the bolt/nut with stainless.
I use these bolts:
