What is a Nib Bolt?


A Nib Bolt is a specialized type of fastener that features small protrusions, or "nibs," on its surface, enhancing its grip within the assembly. These nibs increase the bolt's holding power, making it particularly suitable for applications requiring reliable and vibration-resistant fastening. Widely used in structural frameworks, heavy machinery, and construction projects, Nib Bolts are known for their precision engineering and robust performance.


Features of Nib Bolts


Nib Bolts are engineered to offer unique benefits that set them apart from standard fasteners:-

  • Enhanced Grip: The nibs on the bolt surface improve the connection by providing added friction, ensuring a secure fit.
  • Durability: Manufactured from high-grade materials, they are designed to withstand extreme conditions, including heavy loads and high vibrations.
  • Corrosion Resistance: Coated with galvanized or zinc metal finishes, Nib Bolts are protected against rust and corrosion, ensuring longevity.
  • Precision: Available in a variety of sizes and dimensions, with detailed Nib Bolt tables for easy selection.


Applications of Nib Bolts
