Product Description

1/4"-20 x 2" Self-Drilling Screws / Unslotted / Hex Washer Head / Low Carbon Steel / Zinc / Serrated

1/4"-20 x 2" self-drilling screw in Low Carbon Steel, zinc finish. For drilling and tapping in one pass through metal without a pilot hole.

  • SERRATED HEX WASHER HEAD — serrations under the flange bite the surface and resist vibration loosening
  • HEX DRIVE — wrench or socket driven — the highest practical torque and no bit to cam out
  • ZINC PLATED — an electroplated barrier for interior and sheltered work; it will not survive sustained weather or contact with treated lumber
  • FULL THREAD — threaded to the head, so it grips over the whole length and suits thin or variable stack-ups
  • CARBON STEEL — strong and inexpensive, but it depends entirely on its plating for corrosion protection
RoHS Compliant
