A grating fastener is provided having a base member, a saddle clamp and a swivel clamp rotatably mounted on the base member and spring biased perpendicular to the base member for ease of installation. The fastener is easily installed by rotating the swivel clamp parallel to the base member and inserting the assembly between two adjacent bearing bars and allowing the swivel clamp to spring to its engaged position automatically engaging the bottoms of two adjacent bearing bars. The saddle clamp engages the tops of the same two bearing bars engaged by the swivel clamp.
