These flat head screws are TRUE TITANIUM(TM), specifically commercially pure Grade 2 (CP) titanium. Grade 2 titanium is unalloyed and the most common of all the grades of titanium. It is also the most affordable and used in cooling systems, boat and ship building, as well as many industrial applications such as waste systems. With a minimum yield strength of 39,900 psi (275 Mpa), Grade 2 titanium is comparable in strength to stainless steel. Of course, Grade 2 (CP) titanium is corrosion free in saltwater while stainless steel crevice corrodes dangerously. If you want corrosion freedom and / or lightweight titanium flat head screws at an affordable price, you have found them. TRUE TITANIUM(TM) is a trademark to establish that this product is manufactured from solid Titanium, rather than a coating, plating or color. TRUE TITANIUM, the AT Logo, the Ring around our high strength screws, LOOK FOR THE RING, AFFORDABLE TITANIUM NOW and ALLIED TITANIUM are all trademarks of Allied Titanium, Inc.
