The sharp point provides positive, fast starts in sheet metal.
The fine thread up the shank rolls the material back instead of cutting chips that corrode quickly and cause a rattle in ductwork where vibration is present.
The rolled material creates a larger bearing surface creating a more positive hold.
The fine thread also provides better clamping forces on thinner materials.
Heat-treated to provide a hardened, sharp point and excellent thread cutting capabilities.
The washer face has anti-backing serrations to keep it in place in harsh, vibratory conditions.

Benefits & Advantage

No pre drilling is necessary as the combination of a heat-treated, sharp point and aggressive starting threads with fine thread up the shank provides a positive threading and chip free hole.
