Thanks to Bob MD0CCE for his efforts on Topband!  He made quite a few guys
happy in spite of the seasonal QRN at this time of the year.

I haven't tried these myself but found the following on McMaster-Carr's
website:

http://www.mcmaster.com/#96640a054/=20zftu

P/N 96640A054
	
18-8 SS (Stainless Steel) Flat Head Phillips Machine Screw Black-Oxide
Finish, 4-40 Thread, 1/4" Length, Packs of 100
	$3.59 Pack

The standard Elecraft screws are 3/16" but I believe these 1/4" might work
(someone else please comment if not).  Unfortunately the Black-Oxide finish
is not available in 3/16" stainless.  If these will work, hopefully Elecraft
might offer them in a small quantity as spare parts.

73,  Bill
