help finding a replacement for a unique size hex screw - issue resolved

I have no idea where to ask and I’ve asked just about everywhere and I doubt I’m going to get a response from anyone. I bought a set of wheels from Relations Race Wheels and the center caps only came with 1 of the 2 screw necessary to hold the caps in place. I spent the entire day searching for screws that’ll fit this and have found absolutely nothing.
Here’s all the info I know about this screw:

type of screw: Allen head / hex
Allen size: 6
Tap Size: M8
Thread pattern: 1.25

the screw itself is about 17mm long, and the thread length from bottom to where it meets the head is 9mm and that’s the problem because apparently 9mm long screws don’t exist. I doubt rrw is gonna help and I really don’t want to get rid of these wheels because of a stupid screw.

 

McMaster Carr will have something for you.

 

Can you buy a longer screw and a nut.
Thread the nut on, then cut the screw off, and then back the nut off the screw to “fix” the threads where you cut it off. I’ve done this in the past in the same situation. Where I needed a short screw.

 

Gonna be hard to match that finish.,

Oddly enough man, that looks just like a socket head cap screw I just bought 200 of for work. PM me in the morning. I believe its right, but I will check when I get to work.

 

Okay I think I found something. The thread length from bottom to the head is around 6/16th - 6.5/16th of an inch which translates to 9.5mm - 10.4mm so I’m gonna buy both the 8mm version and 10mm version of this screw.
I don’t want it to be too long and possibly damage the threads because it looks like there is just a solid wall at the bottom of the hole where the screw it supposed to be lol.





kinda hard to see it in that pic lol

 

What is the finish color- hard to tell from photo? Is it like a blackish- green? Looks exactly like a screw I’ve taken off my dirt bike before. I can check my container of motorcycle screws tomorrow AM if it sounds like a possible match.

 

Black

 

yay I found it! Thanks y’all.




Not sure what I’m gonna do with 50 of these lol

 

This what I have.

 

Just be prepared that black oxide finish will rust rather easily. Might be good to give it a squirt of some black satin or matte paint.

 

okay

 

Yaaaay they fit! The head of these screws are slightly larger and the color isn’t spot on but it doesn’t matter because now I don’t have to worry about losing the center caps haha. (The cap has 6 screws and 4 of them are fake and don’t actually thread into the wheel)

thank y’all so much.

I have 48 of these sitting here so lmk if y’all ever need one or two or ten





Edit: RRW said they will send some. Might stick with the new ones I found though

 

I'm planning on painting 8 of the screws black and replacing the current screws with these so they all match. Any tips on painting screws?

 

Paint the exterior portion of the screw head and let it dry thoroughly before installing. Don't paint the threads or the inside of the hex as you'll scratch it up installing it. Once installed paint that inside area using a q-tip and let it dry.

 

okay thank you
