Head Stud & Bolt Kits

In contrast to studs, which are often threaded on both ends and may have an unthreaded middle piece of the shaft, bolts are typically either fully or partially threaded. Additionally, bolts always have a head, unlike studs, which do not.

There are a few things to bear in mind as you weigh the advantages of using studs and bolts. Along with torque pressure, gasket alignment, and overall engine performance, ease of engine installation and disassembly can be a key consideration. The choice of head fastener is frequently determined by the engine's power and acceleration capabilities. A high-end or racing model automobile, for instance, will have quite different engine fastener needs than a car used for daily use.
