[TowerTalk] TEK screws

[K7LXC@aol.com]

      A bunch of people have asked me about TEK screws. Here it is again.

      A TEK screw is a chisel-tipped, self-tapping sheet metal screw. TEK is 
just one manufacturer - there are others. Most any hardware store will have 
them; my country True Value down the street has them. 

     Get the ones with Phillips heads; the quarter-inch long ones should be 
plenty for drilling thru two layers of aluminum elements. They install in a 
couple of seconds with your cordless drill. I haven't seen one of those come 
loose.

     I'll bet you a nickel that riveted joints backed up with a TEK screw 
installed off-axis (per N4KG) will eliminate 'loosening rivet' syndrome. The 
TEK screw will also provide a redundant electrical connection.
