This kind of steep inclination permits it to hold the load as proficiently as square threads although the trailing flank adds additional toughness have a peek at this site due to the wider base.

The underside from the screw is flat, which permits much more floor space resulting in a firmer hold. This screw is often employed for woodwork and attractive extras.
