#10 1/2" (Length) 1/4" (Head Size) Slotted Hex Head Zip-in Screws, Zinc Plated (Bag of 100)

Features * A unique thread design and quality controlled manufacture spell the Zip-in difference. * Zip-in's sophisticated heat treat process allows the screw to taper to a fine, sharp point without sacrificing critical point strength. * Zip-inscrews are faster driving, with a greater capacity for fastening heavier gauges of sheet metal than any other self-drilling type. * Ultra sharp tapered point will not mushroom, break or walk. * Undercut-indented hex washer slotted head always seats flush.
