The invention discloses a foundation bolt stock and a manufacture method thereof, belonging to the field of steel structure construction. The foundation bolt stock comprises a support frame and a location plate frame, wherein the upper end of the support frame is provided with a support surface, a location frame is arranged on the support surface, the location plate frame is of a rectangular-ambulatory plate frame structure and is sleeved on the location frame on the support surface of the support frame, and a plate body of the location plate frame is uniformly provided with a plurality of location holes for installing foundation bolts. Compared with the traditional foundation bolt stock, the foundation bolt stock has the advantages that: 1, due to size control of a location plate and a column bottom plate of the foundation bolt stock, the problem of interference of concrete vertical joint bars and the location plate is reduced; and 2, the consumption of materials is reduced, and the material waste is decreased.
