Frequently Asked Questions
What is the Caterpillar 1T0720 12-point head bolt used for?
A: The 1T0720 is a 12-point (double hex) head bolt used in Caterpillar equipment where high torque is required in tight or confined spaces. The 12-point head allows greater wrench engagement and is commonly found in engine cylinder head and other high-stress fastening applications.
Why use a 12-point bolt instead of a standard hex bolt?
A: A 12-point bolt allows the wrench or socket to engage at more positions (every 30 degrees vs every 60 degrees for hex), which is particularly useful in tight quarters. It also distributes load more evenly around the head, reducing the risk of rounding.
What tool do I need to install the 1T0720 bolt?
A: A 12-point socket is required for this bolt. Do not use a standard 6-point socket, as it may not seat properly and can damage the bolt head. Use a torque wrench to apply the correct torque specified in your Caterpillar service manual.
Is the 1T0720 a high-quality aftermarket bolt?
A: Yes. This is a premium high-quality aftermarket bolt that meets or exceeds OEM specifications for tensile strength, head dimensions, and thread accuracy ??? delivering reliable performance as a direct replacement.

A: This bolt is designed for use in various Caterpillar equipment. Check your service manual or reach out to Propel Parts for help verifying fitment for your specific machine.
Should 12-point head bolts be replaced after disassembly?
A: For critical engine fasteners like cylinder head bolts, Caterpillar typically recommends replacing bolts with new ones rather than reusing them after removal. Refer to your service manual for the specific guidance on this bolt application.
