1/4 in. X 1-1/2 in. Spanner Head Screw, Stainless Steel, Bag of 12

Secure your grates to prevent displacement from heavy runoff flows, pedestrian and vehicular traffic, and to deter potential theft and vandalism when using the Dura Slope® ductile iron frame. Our ¼ in. X 1-1/2 in. Spanner head screws fasten down all Dura Slope® grates to channels and ProFit™ grate locks and provide additional security as screws can only be removed with a spanner drive bit (included). These screws have a sheared tip which allows them to easily thread into the receiving nut of the Dura Slope ductile iron frame. Each iron frame requires two DS-650 screws to secure the grate; one grate per frame. Use our 12 ct. bag of stainless steel screws to help an important part of your stormwater management product function effectively. Hassle-free limited lifetime warranty guarantees the NDS product is free from defects—or we’ll replace it.
