K2 MK2 Insertion Nut with Clip: Stainless Steel Fixing for Secure Rail Mounting

The K2 MK2 Insertion Nut with Clip is a compact but essential component for securely fixing various parts to K2 rail systems. Made from stainless steel with a spring steel clip, this nut slides into the rail channel and remains in position during assembly, ensuring quick, safe, and aligned installations.

According to K2’s official catalogue, the MK2 nut with clip is engineered for rapid insertion and can be used to fasten clamps, brackets, or other support elements to the rail body, making it a must-have for flat-roof and pitched solar PV system builds alike.

Slide-In Installation, No Fuss

This nut is designed to lock in place once positioned, held securely by its clip. It won’t slip down the rail channel, which reduces frustration during module mounting and shortens overall install time.

Prevents misalignment during installation
Holds position reliably, even on angled rails
Speeds up the fixings process for all rail-mounted components

Built to Last in Harsh Conditions

The use of stainless steel makes this component ideal for the UK’s variable weather, withstanding rain, salt exposure, and thermal cycles without loss of performance.

Rust-resistant stainless steel body
Spring steel clip keeps nut anchored in rail
Perfect for both residential and commercial PV builds
