Description
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.
