I have problems when doing my small low level decking.
First, 1 Facism stainless screw striped. It striped at about 15mm from screw head. Can I take it by piler? The screw size is 10G. It is really small space for screws extractor Any suggestion?
Secondly, I accidentally had Fasicm countersink 10G drill bit broken in the merbau when I pre-drill. How can I take it out? Or any ideas to fix it? It is 10G drii bit. Is it too small to apply piler.
All is in the center of decking, not at the corner. Thay are all small.
I draw the pictures to show the position.
