Review on BEIJIAOFLY 4 Pack F150 F250 F350 Boxlink Tie Down Anchors with Anti-Theft Screws - Ultimate Bed Tie Downs Solution (2015-2021) by Marfel Fekete

This is exactly what I need, good price and fits my needs. As previously mentioned, locks are not the most secure. I also noticed that the torx screws aren't security torx (no spacer in the middle), although the included torx bit works for them. I really appreciated having two extra screws in the kit, although when broken screws are a problem, extra screws are not the solution. I did this to minimize the possibility of the bolts breaking - hope this helps you. Since I have a jetted bed, I pierced each hole with a 13/64" bit to remove paint (not metal). Drill (no impact wrench). Finally, I didn't overtighten the screws (the Dewalt drill clutch is set to 5). I'll check the tightness later to make sure everything is ok. It did not last long. , especially compared to a broken bolt.
