In some situations, piano hinges have to be fixed on the end side of the sheet material. Because of the layered structure of many board materials, this side is very sensitive to expansion or splitting when you screw in it; but not with the Dynaplus interior plate fittings screw! The unique triangular-shaped diamond point at the tip of the screw ensures maximum drilling capacity. This allows you to use these screws without pre-drilling.

This special fittings screw is available in two sizes: 3.5x40 and 4.0x40.
