My Jeep JK seat mount bolts were getting rusty and looked scruffy so I decided to replace them. The stock bolts actually are bolts with washers, which I didn’t know but I think the flanges look nicer. You may need a breaker bar or impact drill to get them off and likely a good idea to slightly grease them before putting them in.

I used these to replace the stupid torx bolts that hold the rear caliper brackets on my Cherokee. Do yourself a favor and use these hex bolts.

While the price was right the bolts instantly flash rusted 1 night outside on the truck so recommend shooting with some sort of paint to keep that at bay
