Bought a used set of spoon calipers recently and they did not come with the black mounting bolts to the knuckle. The oem bolts are too short and I can’t seem to find the proper length bolts for it. I called Gotuning because they have the hardware kits but the guy told me they were oem even though they are not. Can anyone tell me where to get these bolts or the proper size/length etc. ? Thanks in advance!

 

Why not just take your oem bolts to a hardware store and ask them to give you the longer of the same thread/pitch/grade?

 

Hardware store probably doesn't carry JIS spec C10.9 flange bolts in M12x1.25mm thread.

That's going to be a really hard bolt to find in any size.

I guess you could do a non flanged bolt and just use a high strength washer. But the head size probably won't be correct.

OP...are you sure the factory bolts don't work?


Edit

A google search showing images of the spoon caliper shows they use socket screws with washers.

That was easy.

Just find the correct size socket screw and washer combination.

Looks like Spoon uses zinc plated socket screws? That's weird. Unless its a C10.9 socket screw. Which also seems weird.

OP:
Use a zinc plated C10.9 socket screw if you can find one.

C12.9 is more common. But you shouldn't buy/use zinc plated C12.9's as that's not safe.

Don't use stainless hardware.
