[NSRCA-discussion] Technical challenge

[Jim Stovall]

Tom,
   
  Actually, what a truss head screw profile looks like is a very thin pan-head style. The one you described is actually called an oval head screw. THis link will show you all the different head types: http://en.wikipedia.org/wiki/Screw
   
  To find a 4-40 screw that is indeed truss or oval head, try www.fastener-express.com
  I also have an Aviall across the street from the airport I work at, I can call and see if they have them that small.

      Hi again all,
   
  Not much input from me lately on this list-but I was wondering if anyone can help me out.
   
  I have been searching just about everywhere on the planet for the following:
   
  4-40 x 3/4 Truss head Phillips , black in colour.
   
  Now if I'm correct, truss head, means oval on the top and countersunk for the seat?
   
  Sorry to bring my predicament to the attention of the list-but I'm about to go nuts about this. Surely somewhere on the planet someone makes these?
   
  Thanks for any help.
   
  Tom
