Knurled bolts are specialized fasteners characterized by their uniquely textured surface, which is designed to enhance grip and facilitate manual handling. The knurling process involves creating a series of ridges or patterns on the bolt's head or shaft, allowing for improved torque application without the need for additional tools. This feature makes knurled bolts particularly advantageous in applications where frequent adjustments or removals are necessary, as they can be easily tightened or loosened by hand. Their robust design and functional surface treatment not only contribute to their effectiveness in various mechanical assemblies but also ensure a secure fit, reducing the likelihood of slippage during operation.
