Dear Sir, my name is John from JTE Australia.I am wondering if you can supply self drilling, hex head screws for use in building steel framed houses. The screws need to have excellent cutting action and be very reliable and strong.The steel sheet we are using the screws in can be up to 3.0mm thick. Can you also supply custom type self drilling metal work screws? We need another type of short screw with a phillips head which is very low profile.If you can please let me know when you have time, that would be appreciated.Kind regards,John.S JTE Australia Show More
