T-Bolt 20/12 M8X20

The K2 T-Bolt 20/12 is a hammerhead screw for insertion into the side chamber of K2 SingleRail 36 and 50 rails. It can be inserted at any point along the rail and repositioned later without removing the rail's end cap. This M8 x 20mm version has a 15.5 x 8.5 x 4mm head and an M8 thread, weighs 0.012kg, and is made from stainless steel (1.4301 / A2) for outdoor durability. Paired with a matching K2 locking nut, it fixes SingleHook flat tile roof hooks and other K2 components to the rail. It is supplied in packs of 100, and is named directly as 'T-Bolt 20/12' in K2's SingleRail System roof hook flat tile assembly instructions, as part of the SingleHook FlatTile fixing set.
