When fastening into wood, chipboard, MDF, plastic, or thin metal sheets, ordinary screws can split the material or require time-consuming pre-drilling. These SPAX universal screws with a 4CUT point and BLAX coating solve that problem by reducing splitting and allowing direct driving without pre-drilling in most wood types.
