I have a garden shed with steel (powder coated) walls. I'd like to attach a piece of timber to the inside of the wall. I'll use the timber to attach hooks for hanging tools.

I don't want the holes I put in the wall to create a leak, and I don't know the best technique to use to prevent it leaking. The shed doesn't have eaves.

2 or 3 bolts through the timber and the shed wall would probably be sufficient when it comes to strength. Would some silicone sealant around the bolts stay watertight for a few years? Is there a better way of preventing water leaking through the bolt holes, or a better way of securing the timber?

In case it matters, temperatures in my location range from -5 to 35 C

I would use some neoprene washers between the exterior bolt head and metal wall. Also put some silicon sealant in the hole/bolt. This will keep water out and stop bolt head from scratching the powder coating and causing rust. Should work fine.


Instead of through bolting get 3 or 4 3/4" disc Neodymium magnets and cement them to that 2x4. each having 20# of pull should more than adequate to hang most tools from. Plus you can re position the hanger and no holes in shed


Is there any way to fabricate some hooks that can go over the walls where the roof and walls meet. I am thinking of several pieces of 1/8" by 1" flat stock bent into a "J" shape to which you could attach a 2x4. Then install hooks in 2x4 to hang the tools on.


Liquid Nails

I would try construction adhesive before drilling any holes in the wall.

The MSDS for Liquid Nails states that the shear strength is 240 psi (1 week cure), and will withstand -18 to 60 C. Should be more than sufficient.
