For concrete walls, the plastic plug couldn't get enough grip so i bought the old skool wood plug (with hole to screw in). however i noticed despite the wood plug being harder than the plastic plug, when i hammer it into the wall, when near 100% insertion, the area getting hammers started to flatten widen up and they feels soft. is this normal or did i mess up?i did apply No Nails in the hole before inserting the wood plug. i did close off the end of the hole with a tooth pick but when i insert it the no nails seems to have entered the hole, so either the tooth pick got pushed out or some punctured occurred. i used a toothpick (smaller diameter than the intended screw) to clear out the path to avoid screw being blocked once it's dried up.I have yet test the plug but i assume i can only insert the screw once to avoid reducing it's grip, so i only have 1 shot and can't do trial & errors. theres 3 plugs for 1 bracket i have now inserted 1. i used no nails on the other 2 to block off the end with a short toothpick chunk.will this work or will it not?It's for a curtain rod bracket. i'm using eyelet so i can only install 3 brackets, each bracket has 3 screws. previously the rawlplug came loose. and a superficial chunk of the wall (shape of the bracket) came off.For the info, the new wood plug is 1.5" length and has been sanded from 8mm diameter down to 6.5mm (still 0.5mm bigger than the plastic plugs). i prepared 4mm diameter screws to fit the plug. since there is no datasheet regarding what screw it accepts, is my selection fit?I used Bosch SDS 6mm drill bit so i don't know why the hole could provide sufficient grip. maybe it did not grip enough of the concrete but the outer layer? via /r/DIY https://ift.tt/2BLxtb2
