I just did another one of these and this time destroyed both screws. I was able to drill & remove without damaging the threads on the shaft. Then I got lucky enough to find some replacement screws on eBay. I estimate the originals to be 10mm in length, so these will likely be a tad long (12mm). Still, this diameter & thread size is rare, so I feel lucky to have found these (can always be shortened if necessary). Here's a link: http://cgi.ebay.com/ws/eBayISAPI.dll...E:L:OC:US:3160. Since I had to buy 100 of them, I'll probably never need them all. If anybody else runs into this issue and needs some screws, PM me your address and I'll mail you a couple. Tim
