Maybe this has been shown on CAUT before, I don’t remember seeing it. The new screw is actually a machine screw with fine threads so it takes a few more rotations, but this is way better than anything else I’ve ever tried. The package shows a bolt, but what actually goes in has a Phillips head and looks like a normal screw.<o:p></o:p></SPAN></FONT></P> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"><o:p> </o:p></SPAN></FONT></P> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Jim Busby RPT<o:p></o:p></SPAN></FONT></P> <P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">BYU<o:p></o:p></SPAN></FONT></P></DIV></BLOCKQUOTE></BLOCKQUOTE></BODY></HTML>
