Head Bolt Set (1-Head)

The FEL-PRO Head Bolt Set (ES 72856) is a precision engine fastener designed specifically for cylinder head assembly and reassembly on vehicles that require OEM-grade fastening integrity. This single-head bolt set is essential for mechanics performing head gasket replacements, engine rebuilds, or valve cover work where adherence to original equipment manufacturer specifications is crucial.

Manufactured to exacting tolerances, FEL-PRO head bolts feature consistent metallurgy that resists thread stripping and maintains clamp load under thermal cycling and combustion pressure. The ES 72856 specification ensures compatibility with factory torque specifications and stretch-bolt protocols common in modern engine designs. This precision threading and material composition allow these fasteners to perform reliably across extended engine operating temperatures without loosening.

Professional technicians and serious DIY rebuilders rely on FEL-PRO fastener sets to ensure repeatability and confidence in critical engine assembly. This head bolt set is ideal for anyone tackling cylinder head work on compatible vehicles, helping to prevent gasket creep and ensuring long-term engine reliability.
