Big Head nut/ fixing

[BugMan]

Soon on my to-do list is mounting the front mudguards on my Sport 250, and was thinking of using the Big Head fasteners but ideally wanted the "nut" version.

Anybody got any suggestions for a supplier?

Thought M5 nuts would be a safer option than the standard M5 bolt's in protecting the tiers and maybe a bit less bending required, but any suggestions welcome?

I used the standard M5 Bighead studs (16mm I think) with foam tape and Nylocs - they've been fine for several years and trackdays. I think I just drilled at 5.5 or 6mm to get the clearance for an easy fit without bending

"foam tape"?

Not looking to steal this thread, but having picked up some new cycle wings at Stoneleigh, I have this job to do as well 

Any recommendations for suppliers of said M5 x 16 big head, male thread fasteners?

Kevin, I just used car builder solutions M5 fixings. Bolted to the frames, then a blob of polyurethane adhesive. Let it set for a few hours, then reach under and flatten the blobs sticking through the fixing. When set, then remove the wing, turn upside down and fibreglass in place. Remember to mask the threads. I used squares of mat about 2 1/2 inches square and about 2 or 3 layers. Allow to set and off you go. Remember the most important bit and that it to heavily key the underside of the wing before and attempt to glue and glass and it will be fine.

Thanks Justin.

Missed that boat then! That's the problem with last minute purchases, never consider what else might be required!
