Metric DIN 316 wing screws / butterfly screws have two wing like projections protruding from the head of the screw. This unique design makes it possible to use your thumb and forefinger to turn and tighten the screw rather than a wrench or other tool ensuring easy rapid assembly and disassembly using only fingers. DIN 316 wing screws are fully threaded and can be used for many applications where quick hand tensioning and clamping is required.
