    soft top / tonneau studs

    Quick question. When fitting the soft top/tonneau studs are people using the self tapping type or threaded with a nut ? Im thinking a nut is much better but probably far more painful to fit in some spots !

    Nuts are more fiddly but I was advised the self tapper ones could cause splits, so I went with nuts.

    Hi Paul

    I used the nuts on both my soft top and tonneau. As Steve said the self tapper ones can cause splits in the fiber glass.

    Regards

    ^^^^^^^^Wot that lot said!^^^^^^^^

    A nut backed stud will never pull out unless you're an absolute gorilla. If a self tapped stud should pull out it will just cause damage that will be a pain to hide.
    I was very surprised way back in the day on A Car Is Born that self tapping studs were used in the Pilgrim Sumo that was being built.

    I used self tapping studs without an issue, but you MUST countersink the hole before you screw the stud in. It's the gel coat that will crack rather than the fibreglass, counter sink the hole takes the gel coat off the stud threads.

    No, I'm not "repairing" it, I'm fine tuning its performance.
