Bolt wanted

[Niknak]

Hi everyone hoping there might be someone on here that deals with fixings, I’m after some 8mm tread size bolts with the biggest flattest heads I can find ideally in black, I don’t want normally with washers or any other suggestions sorry to be blunt the type of thing I’m after are like motor bike fairing fixings but in m8 with a length over 30mm thanks for any help in advance before I get some frame fixings and tap out some m8 stud and make my own cheers

How big do you need the head?

 

[Paynewright]

Have you looked at flanged bolts?

 

[DXX]

A coach bolt will provide the biggest diameter head and shallowest profile, not high tensile though and has square under the head.
Only any good if you are using with a nut as no drive on the bolt head.
Screwfix have stock and plenty on Ebay

A 16mm pan head screw will have a 16mm dia’ head, slot head.

This is an M5 but you get the idea...

No coach bolts are a no sorry but appreciate the idea, really I want a flat underside with a minimum of a 15mm diameter head, I know I’m being picky

Really anoyed I have no access to a lathe anymore or I’d have no issues

@Niknak if you send some dimensions I have a lathe in the workshop, happy to knock some up for you if you can't find any.

 

[Niknak]

Appreciate it but on second thoughts I want a larger head diameter for what I need to do cheers working out the loadings

 

[JOG]

@Niknak loads his nuts!


*my coat is the one with the fixings catalogue in the pocket!

 

[Paynewright]

My only other suggestion (which you may have dismissed already) is black anodized ally fairing washers and countersunk bolts. Quick look on ebay and M8 seem to come out at 25mm diameter...

Or make some in steel.
