5mm wheel spacers, standard bolts?

[Leemitch-91]

As above, wondering if 5mm spacers are safe to bolt on using the standard bolts or if longer ones are required
cheers

Under most circumstances, I would say yes. Check to see how much of the bolt goes through the hub.

I'd say no.
I put 5mm spacers on a few months back. Had probs with rounding the ends of several of my standard bolts, due to them almost not want to go in far enough to start screwing in.
For safety, and the cost of a few quid, buy longer bolts.

You have non genuine bolts i would say and i would be worried that the wheel is not being held on without spacers.

Me amongst many others on here run 5mm spacers on standard bolts with no problems at all.

I've also done it fine.

Nope. The bolts I took off the car were genuine.

Obviously opinions differ, but one would assume that Renault fitted the car with a certain size bolt to suit a particular application. Adding 5mm spacers means the length of the original bolt no longer suits that application.
Each to their own though....

Hence why I said check it first, some do differ, that is a fact.

i think theres an engineers rule that a nut should have about 1.5 of the thickness of the bolt in the nut. so for instance a 10mm stud would need the nut to have 15mm at least of bite on the stud. i dont know if this rule applies to wheels but i cant see it being a bad rule to follow. the thing i see with cheap spacers is the wheel is not sitting on the hub when they are fitted so the nut or stud strenght is more critical

What Stunty said.

I've always increased the wheel bolt length proportionally to spacer thickness. If the bolt required 7 turns before it fully seats for example, it should require 7 turns once the spacer has been added.
