Titanium Reduced Head Screws Source?

apkp777 · #1 07-21-2010, 08:22 PM

Okay,

I have been searching with no success. Does anyone have a source for titanium hardware? There is a titanium screw that has a reduced head (8/32 screw with a 6/32 head). We used these on Boeing aircraft frequently but I don't know where to get them.

I had planned to use them for my fuel tank attach fasteners. I didn't follow up my dimples with a machine countersink thinking that the reduced head screws would be perfect. Now I can't find any. I am reluctant to countersink the holes and don't want to pull the tanks to use a bigger dimple.

I believe the part number is NAS8602-8816.

I did that, all that I get are a bunch of wholesale sites that you have to go through a distributor to access. I was hoping for something a little more simple. Like enter qty and hit "checkout". I realize it may not be that easy.

Check with GAHCO - he seems to be dialed in to the whole aircraft parts supply chain....

Will do! I had looked on your website but didn't find what I was looking for. I had thought to call you.

If you have access to boeing parts, i think the part number is BACB30VF2K..

I'm not sure of the NAS part number, i could look it up if you really need it..

Why do you want titanium?

Titanium paints really well and won't rust. $$ may make it too expensive. I don't know for sure, but I believe that the reduced head titanium fasteners have the same shear strength (or head strength) as a normal head steel. Not that it matters much as I don't think the wing will fall off with either.

Off course it's always cool to say "yeah, I got titanium hardware in my wing". Figure that will trump the EXPERIMENTAL placard in the cockpit.

Yep, I seem to recall that we referred to them as "VF" fasteners. They have a black tip I also recall.
