Question:

Hi, Do you know if anyone used these anchors DR01 instead of the bed bolts on an F150? I dont know what type of thread the bolts on the F150 are. It sure would be a perfect solution if they fit somehow.

Hey Eddy! I do not know of anyone who's done that. From what I can find online it's not going to work though. The Brophy D-Ring Tie Down Anchor item # DR01 uses a 5/8" x 3" coarse thread bolt. It looks like the bed bolts on the 2018 F-150's are 1/2".

Hey Eddy, did you end up finding a tie-down anchor that fits your F-150’s bed bolts? Knowing what worked could help others trying to secure their trucks the same way.
