Torque-to-Yield Bolts Deliver a Perfect Seal without Retorquing.

Using new head bolts for a cylinder head installation is always a good idea, however, on late-model engines that came from the factory with TTY (torque-to yield) head bolts, replacement is an absolute necessity. Torque-to-yield bolts are designed so that they can be elongated beyond their elastic limit into the plastic region without problems. When a specific tightening torque has been reached, the bolts are turned further through a defined angle, which pre-loads them into the plastic region. Consequently, no retorquing is necessary. Although it is a very effective means to get the maximum, uniform clamping load from each bolt, it permanently distorts the bolts, preventing them from being reusable under any circumstance.

Note: When reassembling a cylinder head, make sure the head bolts are designed to exact specifications by a manufacturer you can trust. Victor Reinz supplies gaskets and sealing products to OEMs around the world. They know the industry, and they know the precise bolts necessary to deliver a perfect seal.

M10x1.5x112mm If you are servicing the cylinder head on your car, its required to replace the head bolts because they cannot be re-torqued properly.
