The invention relates to a fastener assembly provided with bolts and suitable for a heavy-load railway with the axle load being 35-40 tons. The fastener assembly is composed of the T-shaped bolts, nuts, flat washers, elastic strips, insulated gauge blocks, an under-rail base plate and pre-embedded iron pedestals. The pre-embedded iron pedestals are pre-embedded on a concrete foundation, and the T-shaped bolts are mounted on the pre-embedded iron pedestals for fastening the elastic strips; the insulated gauge blocks are arranged between a steel rail and the pre-embedded iron pedestals, and meanwhile, the left and right positions of the steel rail are adjusted by replacing the insulated gauge blocks with the different thicknesses; and then the under-rail base plate is arranged under the rail, and elasticity of the fastener system is provided. The fastener assembly provided with the bolts is suitable for the heavy-load railway with the axle load being 35-40 tons. A gauge baffle is omitted, and the design of dove
