Hey climbing folk, Wondering if anyone coud help me please.
I am designing a rockwall for a public park and am looking for bolts that are not easily removable (by vandals). But still can be moved for re preogramming route..
I have heard you can get bolts that come with a special tool that is used to remove/ tighten.. Does anyone know of where these can be sourced.
Thanks
Gyms use Hex bolts.
I have seen in the park Tamper Proof Torx bolts used on those giant net playground things.
Torx are a star like pattern and the tamper proof design has a pin in the centre of the hole to make it harder for someone to undo it without the right tool.
