Car Forum / Porsche / Porshe 944 / January 2009"flap latch housing" triple square size in mm
hi if anyone knows the exact size in mm of the triple square (a.k.a. cheesehead?) socket required to remove the screws on the hatch pin housing unit, please let me know. thanks! -bryan it's the same, I am pretty sure, as the axle - easist thing to do is get a set from Kragen - for about $14 you get four of the drivers, one fits the axle, if the other is different, it's in the set. Beware that they can break, that area is subject to corrosion. by the way, if anyone needs it, I have a rear hatch frame (really really cheap), and a complete rear hatch with good glass, etc (not so cheap) > hi > [quoted text clipped - 5 lines] > > -bryan ** Posted from http://www.teranews.com ** For a simple English guy: What is the flap latch housing? What does triple square mean? Is it what we call hexagonal in the UK?

In the US, Baum tools will sell you a set of Stahlwille XZN sockets for not a lots of money.

The top of the frame connects to the hinges. The rubber wing and surround screws to the frame, and some trim along the top is clipped to the frame. I have a spare one of these frames, by the way, if anyone would like one > On Jul 7, 12:25 pm, "netnews.comcast.com" <no...@nowhere.com> wrote: >> It's called a triple square or XZN fastener, and the size is probably M6 [quoted text clipped - 25 lines] > > -bryan ** Posted from http://www.teranews.com ** > the hatch pin brackets screw into a metal frame to which the glass of the > hatch is screwed. ah > [...] The rubber wing [...] i think this is what "they" call the "flap latch housing". > [...] and surround screws to the frame, ok, so i took these things apart more to see whats going on - on the right side, a rather smart P.O. put garbage bag over the frame and screwed the other stuff into it through the bag, apparently to avoid corrosion, and it worked well. i took the pin and two triple square fasteners out, and what comes off is the rubber wing - and here is where i am confused : on the wing, the unthreaded triple square holes are there alright, but in the center, where the pin goes, are _threads_, as if a part is built onto the wing. a brand-new wing from pelican (OEM-94451203301) has no threads whatsoever. the car is old (1987), so i am wondering if this threaded component - which seems rather fixed to the wing - is part of the frame that broke _from_the_frame_ as i took the wing off? on the "worse" side of the hatch, this apparent threaded part certainly breaks free from the wing with gentle wedging with a flathead screwdriver... i am writing too much now.... so that part broken off of the frame - right? -bryan On Jul 13, 1:26 am, "William Noble" <nob...@nowhere.com> wrote: > the hatch pin brackets screw into a metal frame to which the glass of the > hatch is screwed. ah > [...] The rubber wing [...] i think this is what "they" call the "flap latch housing". > [...] and surround screws to the frame, ok, so i took these things apart more to see whats going on - on the right side, a rather smart P.O. put garbage bag over the frame and screwed the other stuff into it through the bag, apparently to avoid corrosion, and it worked well. i took the pin and two triple square fasteners out, and what comes off is the rubber wing - and here is where i am confused : on the wing, the unthreaded triple square holes are there alright, but in the center, where the pin goes, are _threads_, as if a part is built onto the wing. a brand-new wing from pelican (OEM-94451203301) has no threads whatsoever. the car is old (1987), so i am wondering if this threaded component - which seems rather fixed to the wing - is part of the frame that broke _from_the_frame_ as i took the wing off? on the "worse" side of the hatch, this apparent threaded part certainly breaks free from the wing with gentle wedging with a flathead screwdriver... i am writing too much now.... so that part broken off of the frame - right? -bryan brian - I have no idea at this point what you are talking about - take 3 or four pictures and email them to me (do not post to the group, or reply to this note) - find my email address from my web page, www.wbnoble.com and I'll see if I can help take enough photos that what you are asking about is clearly visible. ** Posted from http://www.teranews.com ** > It's called a triple square or XZN fastener, and the size is probably M6 > (from memory). indeed it is! this is cool, did you see the wikipedia *series* on screw drive types? http://en.wikipedia.org/wiki/Screw no mention of "cheesehead" there... -bryan "Cheesehead" refers to the shape of the head of the screw, rather than the socket / bit type needed to turn it. Kevin That's correct. A Cheese head bolt is any bolt that has a head that is a "Disc with cylindrical outer edge, height approximately half the head diameter". A socket head bolt is like a cheese head except the head is taller. I think that bolts with XZN socket heads should more correctly be called Socket head instead of Cheese head, but what do I know? :0) > "Cheesehead" refers to the shape of the head of the screw, rather than the > socket / bit type needed to turn it. > > Kevin ... finally getting around to post something of a conclusion to this. the key to my trouble was knowing that part 477-827-035-OEM "rubber mounting" exists. i am not certain of the section number, but if you get a catalog, look for "Rear Lid, With Rear Window", it is part number 11, and is not easy to see in the drawing. as of January, 2009 it costs less than 20 dollars. after that, everything makes sense. the "part" i am describing (vide supra) is in fact _two_ parts, one of which is the "flap latch housing", the other a "rubber mounting" that were quite stuck together and needed to be separated with force. was a fun thread though, i learned a few things, and my hatch is working fine - thanks folks! -bryan |
