The K2 T-Bolt 28/15 is a stainless steel bolt for K2's SolidRail and InsertionRail solar mounting systems. Its T-shaped head drops into the bottom chamber of the mounting rail and can be inserted at any point along its length, or repositioned later without removing the rail's end cap. This M10 x 30mm version has a 22.5 x 10.5 x 4mm head and an M10 x 1.5 thread, and is made from A2-70 stainless steel for outdoor durability. It weighs 26.2g. Paired with a matching K2 hexagon flange nut, it fixes roof hooks, rail connectors and other K2 components to the rail without needing access to the rail's open end, and is supplied in packs of 100.
