Triangle Fastener Corporation announces the addition of two new sizes to its line of SD300™ stainless steel bi-metal self-drilling screws. Now available in a #12 diameter in 1” and 2” lengths. They come with a pancake head and #2 square recess and can drill and tap up to .210” thick steel or aluminum. They provide exceptional corrosion resistance and ductility, minimizing the chance of screw failure caused by stress corrosion cracking or hydrogen embrittlement.
The screws are made of 304 stainless steel for optimal corrosion resistance. The low profile pancake head is aesthetically pleasing when used in exposed fastener applications. The screws are TRI-SEAL® coated which minimizes galvanic corrosion when used in aluminum applications and are well suited for attaching aluminum materials like framing and ACM panels.
