lol..i know the feeling..i experienced this many years ago..until i got accustomed to going to a value hardware store and purchasing set screws with tiny points on them so they dont slip..a good hardware store will have hundrededs of different set screws..you should try and go to a local hardware store and purchase some with the little points on them ..thats where i get all my set screws and miscellanius hard ware,,and it will be cheaqper than any hobby store as well..any model hobby has little screws and parts that you can purchase at different stores..the hobby stores mark up these tiny little pieces ..thats how they make there money..yoiu should try and get youre own little screws..and they will be of better qualaty..
