Finer threads are stronger as they have a bigger tension area for a similar diameter thread. Fantastic threads are less likely to vibrate free as they've a lesser helix angle and allow finer adjustment. Finer threads develop larger preload with significantly less tightening torque.[five]

Oval Head- Oval head screws are a mix of a countersunk head in addition to a domed head. Once installed, the screw head protrudes over the material’s surface and gives a decorative search.
