Monster bolts provides access to hard to find fasteners.
Monster bolts provides access to hard to find quality fasteners. The site flowed well to locate what I was looking for.
Today the stainless steel versions are abundant however the specialized black oxide material product with the specific length and size for the small set screws that I required are not widely available as they once were for fastening securely and allowing to make adjustments. Monster Bolts made that choice very easy by offering them. The experience from locating them and purchase and fast shipping exceeded any expectations that I had.
I definitely will revisit their site for their solution for any future build.
