<b>Subject:</b> [TR] How to tell the size of bolt or setscrew from the part number?</font>
<div> </div>
</div>
<div>
<div dir="ltr">I've been trying to figure this out, but am at a loss. Please help
<div><br>
</div>
<div>I have a part number in my parts book. I also have the standard Triumph parts list.</div>
<div><br>
<h1 style="font-size:18px; color:rgb(180,58,102); margin:0px; padding:0px; border-width:0px">
HU910</h1>
<div><br>
</div>
<div>HU is set screw and I'm assuming is fully threaded.</div>
<div>HB on the other hand is a bolt and has a shoulder </div>
<div>I'm assuming the 9 is the bolt diameter. Am I on the right track?</div>
<div>What is the 1 and 0 and can I tell from it, if it is a NC or NF thread?</div>
<div><br>
</div>
<div>I'm aware later Triumph switched the part no. system and that system is more confusing.</div>
<div>Regards, Sujit</div>
