K2 T-Bolt 28/15 M8: The Compact Mounting Bolt for Solar Installations

Designed for precision fastening in solar mounting systems, the K2 T-Bolt 28/15 M8 offers a perfect balance of speed, simplicity and security. Whether you’re working on a residential install or lightweight commercial project, this component provides a solid connection without overengineering.

Quick-Fit Quarter-Turn Locking System

This bolt features a simple twist-to-lock mechanism that slots directly into K2 mounting rails. Once inserted and rotated 90°, the T-head locks firmly in place, ready to be torqued down. This saves valuable time on site, especially when handling dozens of fixings per array.

  • Compatible with K2 28/15 rail profiles
  • Fast, tool-free positioning inside mounting channels
  • Reduces overall install time

Built from Stainless Steel for Outdoor Durability

According to K2’s product data, this T-Bolt is made from stainless steel for corrosion resistance in wet or coastal environments. It retains integrity even under long-term UV exposure and freeze-thaw conditions — ideal for the unpredictable British weather.
