Essential Head Bolts for Engine Assembly

Fel-Pro ES74017 head bolts are manufactured for automotive engine repair and rebuilding. They suit professional mechanics and experienced DIY enthusiasts performing cylinder-head installation. The black finish provides corrosion resistance during storage and service.

Consistent Clamping Under Thermal Cycling

These bolts maintain reliable clamping force as the engine heats and cools during repeated operation. The design resists relaxation that can occur after initial torque, helping to preserve head-gasket sealing over the service interval.

Torque-to-Yield Installation Constraint

Each bolt is intended for a single torque-to-yield tightening sequence and must be replaced whenever the cylinder head is removed. Reuse is not appropriate because the fastener permanently stretches to achieve the required load. Orders of $75 or more ship free.

Questions about this item

How much heat does the Fel-Pro ES74017 Head Bolts generate during continuous engine operation?

As solid steel fasteners, the Fel-Pro ES74017 Head Bolts produce no operational heat themselves; thermal load comes entirely from the combustion cycle they help contain.

What tools or components must I already have to install these head bolts correctly?

You will need a calibrated torque wrench, the factory service manual for torque sequence and angle specifications, and a clean, resurfaced cylinder head and block.

Will the Fel-Pro ES74017 Head Bolts work with an original cast-iron block and aluminium heads from the same engine family?

Yes, these bolts are designed to clamp the factory head-to-block joint; follow the manufacturer's torque procedure for the specific metallurgy combination.
