was unsure how this semi automatic version would work but as it happens it works really well ,just screw the nut rivet onto the selected size thread on the end of the riveter place in the hole and squeeze ,which is the hardest part as the larger rivets need a lot more strength ,i did find that it's easier if you dont open the tool fully for those , once you've set the threaded rivet just open and close the handles once or twice and it releases ,Great nice and simple thanks to a similar design to the old school ratchet screwdrivers you know the ones you push on to twist the screw .anyway it comes in a nice blow moulded case with a good variety of metric and imperial threads .
