Very good torque for bolts

These flexible bolts are designed for powerful, very fast or powerful vehicles. They don't break or rattle. We lingered over a modified Mustang. Many Thanks. Esy to remove your blocky folks' save

Pros
  • Engines and engine parts
Cons
  • I don't remember but there was something

The fit is perfect, the torque flows, so no reuse is possible.

I don't know why Ford is so fond of torque for deforming bolts, but this is one of them. It's a little tricky to tighten properly, but a good tap made the job that much easier. Perfect fit for Ford 5.4L 3V.

Pros
  • Automotive
Cons
  • Expensive

US Ford OEM, or else.

This is a yield point screw. If you removed the pulley and with it this bolt, you will actually need a new bolt when reassembling the motor. These types of bolts require a torque process that stretches the threads to the point of deformation (yielding), which is the maximum required without breaking. If you're using an aftermarket bolt, chances are it won't be the exact stiffness to spring ratio that the engine manufacturer specifies. Trust me - just a few bucks more to get it right and avoid…

Pros
  • Engine parts
Cons
  • I really don't like anything about it, everything is fine
