I replaced the bolts that hold the skid plate to my raceline front bumper and I think they look much better than the hex bolts that RPG includes when you buy their bumper. The ones I installed are stainless steel pan head that takes an allen wrench. I opted for the stainless to match the unfinished aluminum skid but they are also available in a black carbon finish and gold plated anodized. The first pic is the bolts that came with the bumper, the 2nd pic is the pan head bolts that I installed.
