I’m attempting to put the center console back together after doing some repairs. Unfortunately I didn’t take enough photos and I’m having trouble figuring out the correct screws to mount the non A/C Heater Control to the mounting bracket. I’ve looked at the various online vendors and they all seem to show different screw combinations. I’ve attached a photo showing the location of the two screws in question.
So they are both machine screws, and not sheet metal? Are they both black in color? Just trying to narrow it down before I go through my plethora of loose screws, lol.
OK. I’ve apparently lost the original screws. Before I go and order one of those detachable thread checkers, I’m hoping someone knows what the screws are called and where I could order replacements. As everyone knows, sometimes the replacement screw packets from the online stores can be confusing and/or incorrect. Or maybe someone knows the thread type and size.
Sorry to bother you again but is it possible these are sheet metal screws? Everything I find online shows sheet metal and not machine screws. Unless I have the nomenclature of the parts wrong.
Hello,
I believe the screw is as I described.
In the 71 AIM it's:
UPC 1 ASM
Sheet M3
Item... #1 Screw 9427926
The screw is drawn as if it's a Philips head machine screw.
I certainly could be wrong!!!
The AIM drawings are often misleading.
Regards....
Alan is correct, they are both machine screws, of course if Bubba previously owned your car, he installed oversized sheet metal screws, like he did on my 73 with AC.
That’s interesting. The part # Alan references crosses over to sheet metal screws, at least on the zip Corvette site. I want to ensure I use the correct screws so it looks like I’m going to have to do some further research, lol. Thanks guys.
I've went through a phase of buying a large collection of machine and sheet metal screws for use re-installing the interior of my 70. I've already used many in my 68. They are all stainless steel.
They look very similar to the chrome plated steel OEM screws. I do have some chrome plated stainless steel screws. It annoys me to see a rusted screw/bolt head. Ugh. This means in the decades ahead, the interior screws in my cars will be bright and shiny. With me at 84, I can't say the same.
........................................ ...
I try to exercise caution. I don't use stainless steel bolts on any suspension components. I grin and bear it. with OEM or on-the-shelf Grade 8. A Grade 8 rates at ~170,000 psi whereas a stainless steel bolt is ~50,000 psi.(tension). Much stronger stainless steel aircraft rated bolts are available but these puppies go for $30 and up apiece. Just for the hell of it, I have titanium bolts for exhaust manifolds.
Good idea. I purchased a packet of interior screws from one of the online stores. Many are labeled plainly for the individual section of the car but some of the nomenclature doesn’t seem to match the interior pieces (at least to me). Fortunately many on this forum are great at helping me sort through this often times maintenance odyssey, lol.
Hello J,
I've looked at the fastener 'kits' that various vendors sell.
My experience has been that although the fastener will 'work' in the use indicated it may not be the proper configuration or appearance.
An often heard mantra is "please, no screen door hardware to be used"
I believe Chevrolet used over 200 fastener manufacturers, so the exact detail of a fastener can vary.
As you can image the assembly line would NEVER slow for the want of a fastener.
This is why the term TYPICAL is often used in describing original parts.
Regards.....
I use stainless on any non-stressed application.
I also hate rusty crap.
I modify the heck out of anything I feel like---- so the originality of screws is of less than minor concern in my case.
