The slotted retaining washer provides the strongest way of securing a stud.  However it is more intense labourwise, so the moment you need to install more then 200 pieces, please look into the camloc catalogue for other alternatives.  There are also slotted plastic retaining washers that can easily be installed and operateed by hand.
