1. A tactile warning panel inlay system, comprising: a panel having an upper surface and a lower surface; a plurality of spaced-apart tactile warning protrusions extending upwardly from said upper surface of said panel; a plurality of fastener apertures formed in said panel between said protrusions with the upper surface of said panel being continuous and devoid of any other openings except for said fastener apertures; a bolt positioned in each of said fastener apertures; each of said bolts having a head portion and a threaded shank portion extending downwardly therefrom; said threaded shank portion of each of said bolts having a diameter which is less than the diameter of said head portion thereof; each of said head portions of said bolts having an upper end and a lower end; said lower end of said head portion of each of said bolts having a diameter greater than the associated aperture so that said lower end of said head portion rests on said upper surface of said panel; said threaded portions of said bolts extending downwardly through said fastener apertures; an internally threaded anchor member, having upper and lower ends, threadably mounted on each of said threaded shank portions of said bolts below said lower surface of said panel to anchor said panel to a substrate matrix; said head portions of said bolts having substantially the same configuration as said tactile warning protrusions so that said head portions of said bolts also function as tactile warning protrusions; each of said anchor members including an internally threaded tubular portion having an upper end and a lower end; each of said anchor members having a laterally extending flange which extends from the lower end of said tubular portion which has a width greater than the diameter of said tubular portion.
