SV650sy chain guard screws

[garynortheast]

I need to replace the manky chainguard screws on my curvy. As far as I can determine from the AlphaSports fiche, they are 6x16mm. I have a vague idea though, that they have a shoulder on them. I can't get mine off the bike to take a look as they are seized in and the heads are goosed. I shall have to drill the heads off when I replace them but I don't want to do that until I have the new screws. Could someone have a look at theirs please and post a picture or tell me whether or not they are shouldered?

Ta muchly!

If I remember I'll have a look in the morning, can't remember if mine are standard or not though

Thanks for the link there. The bit I want to see is just beneath the head as I had the idea that there is a shoulder there. It's not visible in that picture though.

I want to replace the original screws with a couple of stainless steel Allen screws with a flanged button head; easy enough to get but I need to know whether I have to take account of a shoulder under the head.

**Edit** Oops, just found the second picture and it is indeed a shouldered screw.

instead of a shoulder you can use an oring. just dont tighten it as much. or just buy the proper bolts.

O ring sounds ok, although I'm sure I have some fine pipe of the right diameter kicking about somewhere. I don't want the crossheads in there though, I'd rather have some decent s/s socket screws.

I have replaced shoulder bolts with washers under the head before (choose some washers with the correct OD and drill the hole in centre out to fit over the thread). Use as many washers as you need to get the height of the shoulder. Add an 'O ring or rubber washer ( tap washer) under bolt head to spread the load on the plastic part its holding. I would use threadlock if you use normal bolt with just O ring and can't tighten bolt properly though.
