wont rust and hence will last a long time near the beach. Main use is to replace the nails in some electrical / coax / misting tube clamps by removing the nail and drilling a 3mm hole. Then a cordless drill can drive them into a timber section that would otherwise bend, vibrate etc. with a hammer, due to no supporting structure immediately behind the area that you wish to secure the cable / tube etc.
