Good man, apart from making frames everything else i make is drilled glued and screwed, there's no better site than seen a tightened screw push glue out of the joint, you know it is pulled tight when you see that.
Its is not the strength as both are equal , it is the way the fixing is applied and hold it, Screws pull everything together tighter, nails do similar, have you ever nailed something then nailed the other side only to see the first nailed side has come open, with screws this does not happen,try pulling a screw out with a claw hammer, also if you make a mistake a screw is easily removed, each to there own i suppose, so screw you..
It depends on the quality of wood also , soooooooooooo , if we have crap quality wood, screws will pull out and lone behold so will nails more frequently if i may add, now if we have good solid wood you will see a difference, if not you are doing something wrong , that wood from China will most likely have had 3inch ring nails holding it together, a 1.5in screw would have done the same job no doubt on that cheap Chinese pine.
But make sure they are BIG enough!!
My main worry for PPE is eye protection first and foremost above everything else, a lot of injuries can be repaired but a popped eye ball is done and dusted, several years ago i was trying to get a tyre of a quad bike wheel, i was hitting the end of the tyre lever with a 2lb hammer then all of a sudden i got a sharp pain in the left side of my chest, when i pilled my jumper and tea shirt off blood was squirting out about 4in from a hole in my chest, that was me in the car and off to A@E, after a Xray a 2mm x 3mm piece of metal was found in my chest just short of my rib cage and 2inches further left to the entry wound, now if that was my eye i would most certainly have lost it, they are vulnerable and we only have two so look after them, i do.It goes without exception that PPE should be top of the list.
However, One thing to remember is;
FULL PPE is required,
An unavoidable consequence is that we worry more about eye & Hand/finger injuries when most of these injuries will to some extent heal in time.
Damage to lungs & hearing is progressive/cumulative and once identified it's irreversible.
Ear-defenders and dust extraction are not a luxury they are a requirement!
You need the correct screw driver attachments for those impact drivers as the standard bits shatter pretty quick.
