II Much Fabrication FabBosses

[parsonsj]

FabBosses are ideal for mounting electronic boxes, interior panels, fluid reservoirs, cable and plumbing runs, linkage bases, ground points, etc. They are mild steel, with a wall thickness of .060, so MIG welding to sheet metal is a quick operation. They can also be easily trimmed for welding to irregular surfaces, or notched for mounting to tube.

Using FabBosses minimizes the aesthetic problem of protruding bolts or sheet metal screws, and eliminates that old problem of stripped sheet metal screw holes. It also speeds up the fabrication process in another way: bolt the device to a FabBoss, position it in place, and tack weld. Getting your MIG torch into tight places is always easier than a drill.

One other feature is that the face has a rolled radius so they can be left visible in interior panels.

Watch our blog (see signature)… I’ll be using them all over the place as our Project Unfair goes into high gear.

We’ve got them in stock at $7.50 apiece. For the time being, email me at [email protected]. A new web store is coming soon.

Here's some pre-production FabBosses in action:

They are 0.75" in diameter, 1.25" long, with 1/4-20 threads.

Very cool idea. I need a few of those soon. I'll be in touch!


Edit: I have been reading your blogs, great info in those. Thanks for taking the time to post there. I know it's going to help me a lot on my own projects.

You're welcome, and I appreciate that feedback very much! Sometimes I think only my wife reads it.

Those are really nice. I will be getting some soon for sure. That is exactly what I was looking for to use in a couple different areas of my build.

Great product ! Wish I'd had those available a few years ago.

What's the difference between this and the "nutserts" I've been using for years to do blind fastenings?

[parsonsj]

Greg,

It's a different method that achieves the same thing. The FabBoss has several advantages:
1. You can bolt the device to a FabBoss (or a set of them) then tack weld directly into place. No precision drilling required.
2. A welded FabBoss will never fail in service. Be honest, you think about the nut insert spinning every time you tighten the fastener, am I right?
3. The FabBoss can be quickly trimmed to fit irregular surfaces. Good luck doing that with a nut insert.
4. You can weld FabBosses to tubes. Drilling holes in tubes for nut inserts always leaves chips inside the tube to rattle around, and usually requires a tack weld so it doesn't spin.
5. You can get your MIG torch into lots of tight spots that you can't get your drill into. Let alone the nut insert tool.
6. With a FabBoss, the bolt and insert doesn't protrude into the space on the other side of the sheet metal.

Nut inserts have their place, no doubt. But FabBosses have lots of advantages. I think quality car builders ought to have a supply of both on hand.

And to be fair, I owe you guys some photos and videos about how and why a FabBoss is useful. Bear with us... it's coming.

Now those are good sales pitches! And needed to be posted!

EEEEEEEEEEHHHHHHHHAAAAAAAA

Very cool idea!

Is that the firewall of a third gen camaro/firebird???
