The 1/2" bolt kit contains hardware to hang one target, 2 high strength bolts, 4 washers and 2 locknuts. This kit fits all of our 3/8" and 1/2" gong style targets. Not designed to fit the "static" targets. One kit is required per target, we also recommend a spare. The bolts are high strength but after a few direct hits they will break. High strength bolts will outlast other mounting methods including quick links. Assemble in the following order: bolt, target, chain, washers, lock-nut. Do not fully tightenthe lock-nut. Leave room for the chain to move.The second picture shows how the target will be mounted. The target and chain are NOT included, they are shown for demonstration.
