Without a pilot, the wood will split along the grain, maybe only a tiny amount but the laws of physics make no exception because of an advertised claim. Where there is no metal to wood contact there is no holding power and the pullout strength is compromised. But that’s why the pullout charts use a 2x safety factor. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Dave B. said it clearly, “</span><span style='font-size:10.0pt;font-family:"Cambria","serif"'>I'm not sure why anyone would knowingly expose themselves to a possible construction negligence claim.”.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>My 2¢ 2x<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Cambria","serif";color:#1F497D'>Jim Duncan<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Cambria","serif";color:#1F497D'>North Texas Renewable Energy Inc<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Cambria","serif";color:#1F497D'><a href="http://www.ntrei.com/">www.ntrei.com</a> <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Cambria","serif";color:#1F497D'>NABCEP PV 031310-57<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Cambria","serif";color:#1F497D'>TECL-27398<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Cambria","serif";color:#1F497D'><a href="mailto:ntrei@1scom.net">ntrei@1scom.net</a> <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Cambria","serif";color:#1F497D'>817.917.0527<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> re-wrenches-bounces@lists.re-wrenches.org [mailto:re-wrenches-bounces@lists.re-wrenches.org] <b>On Behalf Of </b>Benn At DayStarSolar<br><b>Sent:</b> Tuesday, July 03, 2012 5:36 PM<br><b>To:</b> RE-wrenches<br><b>Subject:</b> Re: [RE-wrenches] L feet no flashing in shingle roof<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>I haven't read up on the mentioned structural screws yet, but do they specifically state that they can be driven "without" a pilot hole?
