Mudguards

Yeah I've been decently happy with loctite once it's done, it's just that the whole process everytime I put mudguards back on is atrocious.
Not sure where I was going with my question actually, I think nobody has any practical experience with radially-oriented eyelets going all the way through the bridge, I've only ever seen it on Weigle's bike shown above.
I'm mostly concerned whether a nylstop nut will work as well as loctite : I've never had any problem with nylstop nuts on horizontal bolts, but these vertical eyelets on my bike (both at the fork crown and the seatstay bridge) have proven to very prone to rattling loose.
