* Cold forging assembled screws are forged separately then assemble two pieces torether. No heat treatment that destroys the nature of stainless steel
* There is no rust concern as the carbon steel part can be departed after fixing into the steel plate
* Instead of standing on the rooftop, it is also possible to adjust the stainless steel part by a hex wrench from inside
* Only 1% failure rate when using assembled bi-metal screws, but driving traditional welded bi-metal screw can get as high as 15%
