    One of my trimmer racks keeps coming loose on the wall of my enclosed trailer. I attached them with self tapping bolts to the steel frame of my trailer however with all the bumps and commercial use the screws keep backing out.

    I have the thin white walls in my trailer and can't add any 2x4's to bolt the racks too otherwise racks would stick out too far and mowers wont fit (narrow 7x14 trailer) any Ideas?

    I'm about to weld the things to the wall!

    The left side rack is the one giving me problems.

    It doesn't look the greatest. But I've seen people run bolts all the way through the wall of the trailer. Put a lag bolt with the smooth head on the outside the trailer.

    You can try a larger self tapper ,or try moving the rack up or down enough for a fresh hole ,but pretty much any self tapper will do exactly what you have now eventually .
    You can also try a "nutsert " ,which is pretty much a rivet with threads in it .A big steel rivet might work as well depending on how heavy your racks are .
    Any chance you can bolt and nut it to the trailer up-rights ? drilling an access hole right beside the upright or removing the inner panel would probably be required ,but it will be the most permanent method .

    if its just backing out. do this get some clear latex caulk and put caulk on the treads of the screw, this will keep it from backing out and if you ever need to take screw out them come right out. caulk gives enough resistance to screw so it wont back out. i done it to a few of my things and never had them back out again

    Tried latex caulk and silicone too still worked out after a few weeks.

    I think I will cut away the white laminate and have the metal rack bolted directly to the metal trailer frame that way less movement and a tighter grab for the bolts.

    I'll let you guys know how it goes this week.

    Thanks for the help guys.

    you might need a little backer inside the wall ,the uprights are often a very thin aluminum extruded I beam ,and also make sure your using flat and lock washers or locknuts .
