    I remember the days when you couldn't disassemble a motorcycle engine without one of those...

    The trick to undoing screws like that without an impact screwdriver, is to use a drift and whack it on the end before even lifting up a screwdriver. This marginally drives the screw forward releasing the tension. Did it with some brake drums only yesterday, (mind you that tells you that my workshop is a mess and I can't find the impact driver).

    This is a must for removing brake rotor screws! Now that I have a 20V impact, I don't use it as much, but still comes in handy.

    And then you would buy the allen head kit that never had all the correct bolts so your left to reuse one or two of those Phillips screws with their half stripped head...

    This is very important. Without or before an impact driver.

    If the impact driver is of the type that you have to whack with a hammer (as mine is) then both effects are combined into it's use.

    The solid drift gives a more direct forward force to the fastener.

    That is my secret weapon to prevent tampering by operators. Nowadays every one is a mechanic and they always quote somebody from youtube.

    You just need to tighten the screws with the impact but without using a hammer, very easy to loosen again with the impact but difficult with a normal screwdriver. Just let your coworkers know as well.
