Hidden Gutter Hangers bodyRaytec Manufacturing’s BRASS HANGFAST® hidden gutter hangers will now come with a 300 series stainless steel screw. A custom designed and fabricated screw was developed to compliment the holding power of these gutter hangers. Because this material can’t be hardened, a specific stainless alloy is used and extra care and attention to detail when fabricating threads and self piecing point help to compensate for the fact this is not a hardened material.
