Key Features
Precision Threading: The UNF fine thread provides higher torque tension and prevents loosening in high-vibration environments.
R30 Certified: Meets R30 standards for structural integrity, often associated with specific fire-rating durations or load-bearing capacities.
Knauf Engineering: Manufactured to the rigorous standards of Knauf, ensuring consistency across large-scale industrial projects.
Optimized Geometry: The 69.33mm profile is specifically calibrated for deep-anchor or multi-layer material fastening.
Ideal Applications
Heavy-duty steel-to-steel framing.
Industrial machinery mounting.
Specialized fire-rated partition installations.
High-stress construction environments requiring UNF precision.
A Quick Note on "UNF"
In the world of fasteners, UNF stands for Unified National Fine. It has more threads per inch than standard (UNC) bolts. This gives you:
More strength (larger tensile stress area).
Finer adjustment capabilities.
Better resistance to shaking loose over time.
