Interior 1st Gen Most liked posts in thread: Where to find longer screws for the back of the tach?

Don't know the pitch either but if you figure that out the place to look is McMaster-Carr or smallparts.com.

 

Yeah....
I had to go with longer screws when I made my own gauge bracket (for additional pic's, go to my garage). I also used the same three mounting points on the tach gauge. I found a "Truss Head" sheet-metal screw was the same. I'll let you know the size tomorrow when I'm at work (I'm thinking it was a #8 screw), but I'll verify it for you.....

It was a weird thread pitch on my '06, but the metal is somewhat soft. You can just get a screw the right length and run it in there; it'll hold.

 

This is coming from an ENGINEER? :eek6:

I love it Ben. :lol:

Yeah, here ya go....
It's a #8 Truss head sheetmetal screw.
These are "Thread Forming" screws. And at least in my case with the R56, the three holes were in a white plastic, not a soft metal. They worked just fine with matching the stock threads in the tach housing. Mine were SS, you may need to paint yours if you want black.

P/M me your address and I'll be happy to throw these in an envelope for you, if you can't find them locally.

 

Oops, my bad, I didn't read down far enough. The vertical torx screws are M5x1.25, which is an answer to the question the OP didn't ask. :frown2:

Hehe, yeah, I'm giving the profession a bad name. If I've learned anything, though, it's that the best solution isn't always the most correct.

 

OP has a first gen......will these work?

To the OP, you might give Kellen at Cravenspeed a call as they supply new screws for their mount.

 

My dad was an engineer too and he use to say, "never force anything, Get a longer lever". :lol:

# 8 is right, I just went to the local hardware store, with the original as an example. I got a plastic box of stainless steel screws with the same pitch, but they were an inch and a quarter long, I cut it down and smoothed the end on a grinder. It screwed right in, no problems.

Thankyou.... Thankyou.... Thankyou Verrrrrry munch.....

Elvis is leaving da house....

 

I just checked. R56 and R52 tachs use the same screws (I happen to have both handy from my work on InvisiLens).

 

Yes

 

I do remember the same slight resistance and when I measured the two screws, the #8 had a slightly larger root diameter but the threads were right on. Remember, these are thread forming screws. When they were originally installed at the factory the screws formed the threads at the time they were inserted. The #8 is doing something similar. The threads are matching but there is slight resistance with the #8 due to the slightly larger root diameter.
I have even re-installed the original screws and they continue to work fine. Just make sure about your length.

 

In other words, when all else fails, "make it fit". That has always worked for me. :lol:

I got mine at Lowes hardware.....

 

Craven Speed sells the ones you need. They use them for their attachment holders, that mount behind the rev counter.
