MKT HVAC Screws

MKT HVAC Screws

Sharp Pointed and Fine Thread
MKT’s HVAC Screw is a sharp pointed, fine thread screw for use in sheet metals of several gauges.

No Pre Drilling and Chip Free Hole
No pre drilling is needed as the combination of a heat treated, sharp point and aggressive starting threads with fine thread up the shank provides a positive threading, chip free hole.

  • 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.

  • The MKT HVAC Screw is

    • available in economical bulk packs only,

    • a lower cost option compared to other sharp pointed, fine thread screws,

    • 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.
