Frequently asked questions
What tool do I need to tighten it?
You need a hex (Allen) key that matches the socket size in the screw head.
Is it suitable for humid or outdoor use?
Stainless steel 304 resists rust better than plain steel, but it is not immune to every corrosive environment. Check the conditions of your application before using it outdoors.
