Cam gear bolts

[czy18e]

Can anyone please tell me where to get some factory RB cam gear bolts?

Or bolts of there type? Think they are 7mm which is very rare.

They're M5 (8mm head), about 20mm long.  Nissan would have them but I would be happy to run any 8.8 grade bolt at the right length....so check bunnings...

[czy18e]

M5? Thanks mate. Is that like 7 mm? What do you mean by 8.8 grade?

[chiksluvit]

Tensile strength

M5 is 5mm metric

[czy18e]

6mm is too small and 8mm is too big. I thought M5 would be 5mm?

[czy18e]

5mm is too small.

M5 is the diameter of the bolt and does mean a 5mm threaded section. the head is 8mm so you would use a 8mm spanner.

8.8 is the tensile strength of the bolt, it is printed on the head of a metric bolt. It's important you don't buy a replacement with a lower tensile strength.

I don't have one to measure the length handy but from memory they are about 20mm long (from the underside of the head to the end of the thread). If you can't confirm the exact length just screw a bolt in lightly and make sure it tightens the plate/cam gear in place before the thread bottoms out. If it is too long there is no issue cutting it shorter to suit.

So you would buy 8 bolts described as High Tensile (8.8 grade) M5x20mm, for example http://www.ebay.com.au/itm/M5-5MM-HIGH-TENSILE-NUT-BOLT-X10-SETS-M5-X-20MM-ZINC-GOLD-8-8-FREE-POST-/131933153719?hash=item1eb7d429b7:g:Dk8AAOSw8oFX0gMP

Thanks so much for the info mate but 5mm is just too small. I'll try find what your saying but in an m7 or 7mm.

[GT-R David]

It's an 11mm head from memory. Could be M7.

But I'm sure it's not M5 with 8mm head.

Thanks for persisting, made me get off the keyboard and rummage around to find and measure one .

Confirming they are actually

M7x20mm (11mm head)

[czy18e]

Legend. They would be just a basic metric fine thread hey?

[czy18e]

...and nowhere sells them.
Wanna sell yours? Lol

Try searching for M7x20 set screw.

These are the wrong length but you get the idea:

Where are you? If you are in a capital city, try United Fasteners - if they don't have them then they aren't worth having.

yeah they are 1.0 pitch. "fine" or "coarse" changes depending on the bolt size, I'm not sure if 1.0 is considered fine or coarse for M7

[Duncan]

and there's always Nissan...I need mine if the spare engine ever goes back together....

Coarse is 1.0mm  Fine is 0.75mm

A good engineering supplies shop will have them (maybe not Bunnings).

Thanks so much everyone [emoji106]
