Frequently Asked Questions

What is this nut used for?

It's a square nut designed to sit within the KlickNut M8 channel of Schletter system rails, giving a fixing point for a matching bolt from outside the rail.

Why is the nut square rather than hexagonal?

What is the KlickIn component used for alongside this nut?

The KlickIn click component (SLT-129010-008) simplifies inserting this square nut at any point along the rail's KlickNut M8 groove, rather than needing to slide it in from the rail end.

What wrench size fits the matching bolt?

This nut has a 13mm across-flats dimension; check the specific bolt you're pairing it with for its own wrench size.

Is this nut suitable for outdoor use?

Yes, it's manufactured in stainless steel, giving good general corrosion resistance for outdoor PV mounting applications.
