Note: Please don't screw in the bolt too tightly. Due to the small size of the hex keys and bolt heads they can strip if screw tightly and then you may not be able to remove the bolt. If the hex key doesn't turn the bolt then check the hex key and bolt head if you have stripped one of them. Some sizes have flat head screw bolt heads (use smallest flat head screwdriver in mini screwdriver set).
We have checked all threads of the sizes in the listing that include a bolt. We have checked these by inserting the bolt gently, so these sets come with the bolt already inserted. Gently turn the bolts anticlockwise to remove.
