Summary:A base plate for fastening a rail to a fixed bottom support, having a through-opening which runs from the upper side of the base plate to its underside and through which a clamping bolt having a polygonal head is inserted from the underside, forming in the underside, a receptacle, wherein the head of the clamping bolt is seated. Each side-face of the bolt head has a face for contact formed on the circumferential wall, which extends for part of the length of a side-face of the bolt head, and against which side-face has, planar support. The faces for contact on the circumferential wall are spaced apart from one another. There is formed in the circumferential wall of the receptacle, between each pair of adjacent faces for contact, a recess wherein there is no contact between the bolt head and the circumferential wall of the receptacle.
