Bindery equipment often has to be serviced or adjusted in hard-to-reach spots. The lowly allen screw is one item that can give an operator fits when removing or replacing. Quite often the allen is dropped into an impossible-to-reach spot...repeatedly.
Folding machines, scoring or perforating machines, saddle stitchers and perfect binders all have lots of constant vibration when running. So screws work their way loose and fall out.
Or over time, the heads of the allen screws get rounded out from repeated tightening and loosening, so they need to be replaced. Whatever the reason, those hard-to-reach spots sometimes need to be reached.
This video shows a quick tip to make this frustrating task easy and fast, and works well whether you are taking the screw out or putting it in.
