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.
