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.</span></font></p> <p class="MsoNormal"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial"> </span></font></p> <p class="MsoNormal"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial">Jim Busby RPT</span></font></p> <p class="MsoNormal"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial">BYU</span></font></p> </div> </blockquote> </blockquote> </div></span></font> </div> </body> </html>
