Help! Busted screw (grumble)

[baders]

Thanks DB. Having been an engineer for some 35 years, believe me when I say the screws that came with my kit were sub standard. I use the correct method of installation. The things were falling to pieces even gently extracting them. That said, below is what I have done to remedy. Hopefully this can help someone else.

1) Attempted to "slot" the broken off screws to use a small flat screwdriver to remove. Not successful.
2) Drilled two shallow 2mm holes 180 deg apart;



3) I then used my smallest side cutters to gently grip the broken piece and unscrew;



4) This left shallow but wide holes with still plenty of meat for the new screws to grip;



5) The offending rubbish screws plus a good 4 gauge (3mm) x 9mm screw from Bunnings on right;



6) The finished job;
