Secure your grates to prevent displacement from heavy runoff flows, pedestrian and vehicular traffic, and to deter potential theft and vandalism. Our #8 X 1 in. Phillips flat head screws fasten down Spee-D® Channel standard plastic, galvanized steel, and decorative iron grates to Spee-D channel drains, and 3 in. Pro Series Channel™ grates to 3 in. Pro Series channel drains. These screws have a pointed tip and coarse threads that easily drive into the Spee-D Channel grate seat, and into pilot holes molded in the 3 in. Pro Series Channel grate seat. Use our 48 ct. bag of stainless steel screws to help an important part of your stormwater management product function effectively.
