Anti-Seize Thread Lubricant
Every vintage Honda has that one bolt — the one that rounds off, snaps its head, or takes a torch and an hour to free. Anti-seize is how you make sure future-you never fights it again. A thin coat on the threads and every fastener comes apart clean the next time.
Why You Need This
The problem is metal on metal for fifty years. A hard steel bolt threaded into a soft aluminum case slowly corrodes and seizes, until the head twists off before the bolt ever moves. Anti-seize puts a barrier between the two so the threads stay free — smooth going in, and smooth coming out whenever you need to pull that cover again. The rule of thumb is simple: any steel bolt going into aluminum gets a dab of anti-seize.
It works on more than case covers. Axles, exhaust studs, and just about anything that threads together benefit from it, and it’s rated up to 1200°F so it holds up on hot exhaust hardware.

How to Use It
- Put a thin, even coat on the clean threads — you don’t need much.
- Thread the fastener in and torque it to spec for its size.
- Any steel bolt going into an aluminum part is a candidate; so are axles and exhaust fasteners.
Go easy near spark plugs — if the compound gets onto the porcelain of the electrode it can cause erratic spark and ruin the plug.
Frequently Asked Questions
Where should I use anti-seize?
Anywhere a fastener needs to come apart again later — especially a steel bolt threaded into an aluminum casting, and anything that sees big temperature swings like engine side covers and exhaust mounts. That’s most of the fasteners on a vintage Honda.
Anti-seize or thread locker?
Opposite jobs. Anti-seize is for fasteners you’ll remove again and want to keep free. Thread locker is for the few that should stay put — parts that see hard vibration and don’t need routine removal. If a bolt needs locking instead of lubing, reach for our Hondalock thread locker (the medium/blue one covers most jobs).
Do I use it on stainless bolts?
Yes — brush a little on the threads. Stainless fasteners can gall against aluminum over time, and a thin coat keeps them coming apart clean. It’s worth doing on the stainless Allen bolt kits we stock for most models.
What brand is it?
It varies by what’s in stock — we supply an equivalent anti-seize under whatever brand is available. Copper-type or aluminum-type both do the same job here; the important thing is having something on the threads.
