ibexman Posted March 3, 2010 Share Posted March 3, 2010 Whats best fat or thin thread or may be self drilling???? Quote Link to comment Share on other sites More sharing options...
timmymac Posted March 3, 2010 Share Posted March 3, 2010 I would imagine a fine thread and probably not self drilling so you can use a smaller drill to keep it really tight,could be wrong but at a guess its what i would do or use rivets.

FridgeFreezer Posted March 3, 2010 Share Posted March 3, 2010 My sheet tin shed uses self-drilling fairly coarse thread screws (hundreds of the b*ggers), wlthough it may help to describe what you're trying to do - horses for courses and all that.

Ally V8 Posted March 3, 2010 Share Posted March 3, 2010 If you sharpen a thin punch then use it to create a hole,the inward curved edge can create extra area for the threads of the screw to dig into - if that makes sense. Quote Link to comment Share on other sites More sharing options...
Night Train Posted March 3, 2010 Share Posted March 3, 2010 A deep, coarse thread could turn the thickness of the sheet into one turn of thread. That may, in some cases, be better then a couple of turns of finer thread. I prefer inserts and rivnuts on thin sheet. Quote Link to comment Share on other sites More sharing options...
heath robinson Posted March 3, 2010 Share Posted March 3, 2010 If you want to achieve the same effect as the screws fixing my factory galvy light-guards to my bodywork, then it's all about the quick, coarse screw In all seriousness, those things have one fights with stonework, foliage, and farm machinery. I undid them (For what is i suspect one of the very few times since '84, and certainly the only time in the last ten years) a while ago, and they did back up as tightly as ever.

LandyManLuke Posted March 3, 2010 Share Posted March 3, 2010 I'd definitely say a thicker, coarser thread, so that the thin sheet becomes one thread of a 'nut', as mentioned above. Quote Link to comment Share on other sites More sharing options...
