Round head knurled hub bolts are a type of fastener that is used to secure a hub to a shaft or other component. The head of the bolt is typically round in shape and has a knurled surface for grip. Knurling is a manufacturing process that creates a pattern of small ridges on the surface of the bolt, providing a better grip for tightening or loosening the bolt.

Round head knurled hub bolts are commonly used in applications where the bolt needs to be tightened securely and may be subject to frequent adjustments, such as in machinery or equipment. The knurled surface provides a better grip, making it easier to tighten or loosen the bolt with a wrench or pliers. The round head design allows for a large surface area for tightening, which can help distribute the clamping force evenly and prevent damage to the hub or shaft.

These bolts are typically made from high-strength steel or other durable materials and are finished with a rust-resistant coating, such as zinc or black oxide to protect against corrosion. They come in a variety of sizes and thread types to fit different applications.

Round head knurled hub bolts are a reliable and durable fastener solution that is commonly used in a variety of industrial, automotive, and manufacturing applications.
