I found the place to buy the odd and weirdest nuts and bolts in Malaysia

I was replacing a window handle connected to metal window frame where the old screw was worn out by wear and tear moisture. The screw was quite different from normal screws as it is to be put into metal frame and also it has very fine edges unlike the standard ones.

I searched high and low from all the hardware shops but couldn't not find it but I was lucky one of the hardware shop guy referred me to this place at Seri Kembangan that specializes in selling all kinds of screws and bolts.
