You can’t bleed with a socket on it. The problem is that the crappy bleed screws that are inappropriately metric because they are made in Asia also have crappy threads, a crappy seat, and are made of crappy metal. <br><br><div id="AppleMailSignature" dir="ltr">Sent from my iPhone</div><div dir="ltr"><br>On May 23, 2020, at 12:57 AM, PaulHunt73 via Mgs <<a href="mailto:mgs@autox.team.net">mgs@autox.team.net</a>> wrote:<br><br></div><blockquote type="cite"><div dir="ltr">

<div><font size="2"></font><br></div>I can see why — it is a uselessly tiny

anything that needs actual tightening, like a bleed screw.
