    An ongoing issue for some of us Sportster owners. Mine is particularly odd in that there's only one bumper bolt front and rear on the wings, the stay doesn't go full width of the wing and the offside rear one is swivelling in the hole and rusted onto it's nut.

    I probably need to find some slotted head bumper bolts as shouldered ones won't work on worm out fibreglass holes. Anyone know where to get some?

    I have used this kind of bolt Untitled.jpg extensively to attach bumpers, wings and down the centre line of the bonnet.
    Search eBay for Button Headed bolts and buy stainless versions and nuts, they won't rust

    Those on my Berlinetta came with the car and the heads are 16mm. IF you mean this (see picture) try to google for “stainless DIN 921“. For M8 the available head size is 16/20/25mm and may profit from additional polishing/rounding the edges. Quick search found uk based offers about 5pounds each but should be possible to get them much cheaper. Link to see what I’m talking about: https://www.accu.co.uk/large-slotted...-SFPL-M8-20-A1
    For bumpers I have used domed nuts (front) and regular hex head with polished heads (done myself to remove description) (back)

    Found something that may do the job. M8x30mm with 20mm mushroom slotted head.

    Use a nice large chromed bumper bolt. Carefully file two generous flats across the end 6mm of the thread. Forget nyloc nuts and use a shakeproof washer and plain nut. You can then assemble it all until finger tight. Then use a small spanner, or the end faces of Mole grips, to grip across the flats to prevent the bolt turning while you use a spanner to fully tighten the nut.

    I did try doing just this with the existing setup but the nylon refused to budge, angle grinder next.
