The strength bolt for attaching the G3, Aggressor and Tactical Spirit stocks and other Detonics adapters, as well as the original Sa58 folding stock, is a more perfect variant and a replacement for the inconvenient original bolt.
Advantages of the G3 screw:
Compared to the original screw with a screwdriver notch, the G3 screw is equipped with an Allen head (hexagonal internal profile No. 8), which allows a safer and more firm tightening of the stock to the weapon without the risk of tearing off the tightening edges.
The bolt has a partially flexible collar head, which after tightening permanently pushes the stock to the body of the weapon. This significantly reduces the risk of stock release.
