We have been selling these custom modified truss self tapping screws since 2004. As of 2018 we supply this part in plain 18-8 stainless steel, black oxide finish shown here, satin sheen brown, and satin sheen grey shown below.

Originally the black version was supplied with a painted head as well but we switched over to the black oxide finish to lower the risk of chipped paint inside the phillips drive to drive the cost down as well. Turnaround time on black oxide is also drastically faster at just 1-2 days compared to 3-4 weeks for the painted hardware, assuming you have the plain stainless steel version in hand. All finishes are supplied to our customer on annual blanket purchase order basis with same day shipments when release directions are sent our way.
