K2 T-Bolt 28/15 M10: The Fast-Locking Rail Fixing for Solar Mounts

Designed for speed and strength, the K2 T-Bolt 28/15 M10 delivers quick-fit functionality and dependable hold for structural solar applications. It’s an essential part of K2’s mounting system – especially where rapid installation and long-term reliability are key.

Fast and Easy Assembly with Quarter-Turn Engagement

This bolt uses a smart quarter-turn locking mechanism that grips into the base of K2 mounting rails. Installers can align and tighten the bolt in seconds without repositioning components. The T-head sits securely in the slot and resists rotation once fitted.

  • Tool-free insertion into K2 system rails
  • Prevents slippage and rotation during tightening
  • Reduces time spent on repetitive installations

M10 Thread for Heavy-Duty Applications

Its M10 thread makes it suitable for solar arrays with larger modules, higher wind loading, or structural mounting demands. Whether you're installing residential solar panels or a commercial EV canopy system, this bolt ensures firm anchoring across the board.

Resistant to the Elements
