Stainless Fasteners: Use the Anti-Seize
Every Airkewld stainless fastener kit comes with nickel anti-seize. It isn't a bonus — it's what keeps a stainless bolt from locking up halfway in. Here's why it matters and exactly how to use it.
Stainless Doesn’t Forgive Dry Threads
Stainless hardware is the right call on a classic VW — it doesn’t rust, it looks right for decades, and it comes back off years later when you need it to. But stainless has one weakness every builder needs to know about: galling.
As a stainless nut and bolt tighten, the threads slide against each other under heavy pressure. Without something between them, the surfaces can tear and grab, and the metal starts to fuse. It shows up as a fastener that suddenly gets tight halfway down. Push past that and it locks solid — usually for good, and usually it has to be cut out.
We’ve seen it happen a few times over the years: too little anti-seize, and the two fasteners welded themselves together. Let’s keep that from happening to you.
The fix is simple and it’s already in your box. A generous coat of the supplied nickel anti-seize on the threads keeps the two surfaces apart, so the fastener runs down smoothly, holds, and comes back apart when you need it to.

Step by Step · The Way We’d Do It
Same routine for every stainless fastener in every kit — beam bolts, shock bolts, pedal, steering box, link pin, all of it.
Start Clean and Dry
Wire-brush any threads you're going into — a nut, a captive thread in the chassis, a threaded hole. Old grease, rust and grit are what start the trouble.
Coat the Threads — Generously
Use the nickel anti-seize that came in your kit. Cover the threads over the full length that will be engaged, all the way around. A dab on the tip is not enough. More is better here; you'll wipe the extra off in a minute.
Threads Only
Keep it off the underside of the bolt head, off washers and off the faces the parts clamp against. Anti-seize belongs in the threads, where the two metals slide against each other.
Run It In by Hand First
Start every fastener by hand and get it as far as you can before a wrench touches it. If it suddenly gets tight or gritty partway in, stop. Back it out, clean both parts, re-coat and try again. Forcing it is how a bolt locks up for good.
Tighten Smooth and Steady
Use a hand wrench with an even, steady pull. Fast, hammering tools build heat in the threads, and heat is what stainless doesn't like.
Wipe the Excess
Wipe away whatever squeezed out around the nut and the exposed threads. Left wet, it collects road grit, and that grit finds its way back into the threads.
Torque: we don’t publish torque values for our stainless fastener kits yet. Anti-seize makes threads turn more easily, so on anything critical, call or email the PROs before you put a torque wrench on it.
The Mistakes That Lock Stainless Up
Every one of these is avoidable. All it takes is the anti-seize in your kit and a minute per fastener.
Installing It Dry
Stainless on stainless with nothing between the threads is the classic setup for a bolt that locks up halfway in. Every Airkewld stainless kit ships with nickel anti-seize for exactly this reason. Use it every time.
Using “Just a Little”
This is the one that bites people. A thin smear wipes off on the first few turns and leaves the rest of the thread bare. We've seen two fasteners weld themselves together from too small an amount. Be liberal, then wipe the excess.
Putting It Everywhere But the Threads
The threads are where the metal slides and where the damage happens. Coat the threads. Leave the underside of the head and the washers alone.
Running It In With an Impact Gun
Speed builds heat, and heat in stainless threads is how they seize. Start by hand and finish with a hand wrench.
Forcing a Fastener That Binds
If a stainless fastener tightens up before it should, more force makes it worse — the threads are starting to tear into each other. Stop, back it out, clean, re-coat, start again.
Leaving the Extra On
Wet anti-seize sitting on the outside of the joint is a dirt magnet. A quick wipe with a clean rag finishes the job.
Every Airkewld Stainless Fastener Kit
If you scanned the label on one of these, you’re in the right place. Each one ships with nickel anti-seize.
The Questions We Get Most
Do I really need anti-seize on stainless bolts?
Yes. Stainless steel is prone to galling: as the threads slide together under load, the metal surfaces can tear and fuse to each other. Once that starts, the fastener locks up and usually has to be cut out. A liberal coat of nickel anti-seize on the threads keeps the two surfaces apart. That's why every Airkewld stainless fastener kit includes it.
Why nickel anti-seize?
Nickel-based anti-seize is the type made for stainless steel, and it's what we put in every stainless kit. Use what came in the box.
How much should I use?
More than you think. Coat the threads all the way around, over the full length that will be engaged. Too little is the mistake we see — a small amount can wipe off as the fastener goes in, and we've seen fasteners weld themselves together that way. Be liberal, then wipe off the excess once it's tight.
Does it go under the bolt head or on the washers?
No. Threads only.
What torque should I use with anti-seize?
We don't publish torque values for our stainless fastener kits yet. Anti-seize makes threads turn more easily, so don't guess on anything that matters — call or email the PROs before you torque a critical fastener and we'll walk you through it.
I ran out of the anti-seize that came with my kit. What now?
Use a nickel-based anti-seize from any parts store. Same rules: threads only, be liberal, wipe the excess.
A stainless bolt got tight halfway in. What should I do?
Stop. Don't force it. Back it out slowly, clean both threads, check them for damage, re-coat generously and run it in by hand again. If it won't back out or the threads look torn, call us before you do anything else.
Real Humans. Real Phones. Real VW People.
If a fastener binds, the threads look wrong, or you need a torque number — reach out before you force anything. We pick up the phone. We answer the email. That’s the Airkewld way.
