- 8mm threaded solar rail slot nuts offer a easy quick method of securing clamps to our K2 system. PV rail nuts PV Rail Nuts M10 slide along length of channel, they are suited to accept mid and end clamp fittings. These will then hold the tolerances required to secure solar panels to roofs. The PV rail nuts are a spare part.
