What is the purpose of a left-hand thread bolt?

A left-hand thread bolt is designed to tighten when turned counter-clockwise. This is used in specific applications where the rotational forces of the engine could otherwise cause a standard right-hand thread bolt to loosen over time.

Why use a 12-point bolt head?

A 12-point bolt head offers more points of contact for your socket compared to a standard 6-point bolt. This can be beneficial in tight engine bays, providing better grip and reducing the chance of stripping the bolt head during installation or removal.

Does this bolt come with any special installation hardware?

This product is a single hub bolt. It does not include any additional installation hardware; you will need to use the appropriate socket and any necessary thread locker as specified by your vehicle's service manual.

Product Details

When you're rebuilding the front of your engine, especially if you're working with a timing cover or a specific accessory drive, you might run into a situation where you need a specialized hub bolt. This 12-point, left-hand thread hub bolt from COMP Cams is designed for those precise applications where a standard bolt just won't cut it.

This bolt features a 12-point head, which gives you more points of contact for your socket compared to a traditional 6-point bolt. This can be really helpful in tight spaces or when dealing with a stubborn fastener, as it allows for better tool engagement and can reduce the risk of rounding off the head. The left-hand thread is a critical feature for certain engine setups, ensuring it tightens in the correct direction for the application and won't back out under normal operation. It's a well-built piece that's made to handle the specific demands of engine component installation.

If your project calls for a left-hand thread hub bolt with a 12-point head, this COMP Cams part is a solid option. Always double-check your service manual to confirm the thread direction and size needed for your specific engine build.
