Review DORMAN/AUTOGRADE Cap Screw hex Head grade 5/8-11 Inch

Introducing the Dorman/Autograde 803-640 Cap Screw, a versatile and durable fastener ideal for various automotive applications. This cap screw boasts a hex head design with a grade 5 finish and a thread pitch of 11, making it suitable for bolts and screws in the 5/8-11 size range.

The hex head design of this cap screw offers several benefits. Its six-sided shape facilitates a more even distribution of torque, reducing the risk of damage to the screw or the material being fastened. This design also makes it easier to apply torque with a socket wrench or a torque wrench, ensuring the screw is securely tightened to the recommended specification.

Made from high-quality steel, the Dorman/Autograde 803-640 Cap Screw boasts a grade 5 finish. This grade signifies that the screw has undergone a rigorous heat treatment process, resulting in increased strength and superior resistance to corrosion. This makes it an excellent choice for automotive applications where the screws will be exposed to harsh environments, such as under the hood or in the wheel wells.

The thread pitch of 11 on this cap screw means that there are 11 threads per inch. This is a common thread pitch used in the automotive industry, particularly for applications that require a strong, secure fastening. The threads are designed to provide a firm grip on the mating component, ensuring that the screw remains in place even under considerable stress or vibration.

In summary, the Dorman/Autograde 803-640 Cap Screw is a robust and reliable fastener, perfect for automotive applications that demand strength, durability, and corrosion resistance. Its hex head design, grade 5 finish, and thread pitch of 11 make it an essential addition to any automotive toolbox or repair project.
