ACDelco GM Truck Bed Liner Kit with Screws & Retainers - Secure Cargo Protection

These fit the lower larger holes in my GMC truck Bed liner. Nice tight fit. Came with plastic pop rivets to hold them in place when opened to access tiedowns. Easily popped back in place to stop any foriegn matter from getting in between the bed liner and the bed. I was also surprised that the package included special black screws designed to mount the bed liner to the truck bed. As special note the top holes are a smaller size of almost the same product but without the little tabs that hold them in place when open. If you geet these smaller units keep a bag in the cab to keep them together when using the upper tiedowns. Very pleased.
