Nib Bolt

Flat Countersunk Nib Bolts are threaded fasteners with a flat head and are tapered underneath the head. The Nib bolt has a nib which protrudes from the taper that will fit into a countersunk hole with a slot in it which is designed to hold the nib in place as the nut is tightened or loosened on the bolt.Flat Countersunk Nib Bolts are designed to sit flush on a surface.They are commonly called Plow Bolts as they are often used to affix a blade to the edge of a plow. Nib bolts, also known as flat countersunk nib bolts or plow bolts, are designed for secure and flush mounting in various applications. Featuring a flat head with a tapered underside and a protruding nib, these bolts are engineered to fit into countersunk holes with a slot that holds the nib in place as the nut is tightened or loosened. Ideal for use in securing plow blades or other components, nib bolts provide a smooth, flush surface and reliable fastening.

Introduction to Nib Bolt

Nib bolts are specialized fasteners designed for applications requiring extra grip and stability. These bolts feature small protrusions, or "nibs," underneath the bolt head, which dig into the material being fastened, providing enhanced resistance to loosening under vibration. Nib bolts are commonly used in automotive, construction, and heavy machinery industries, where secure and durable connections are crucial. At Pankaj International, a renowned fastener manufacturer in Ludhiana, we produce top-quality nib bolts that meet the highest industry standards.
