447-015 1 1/2 PVC CAP (SLP)

A unique thread design and quality controlled manufacture spell the Zip-in® sheet metal screw difference

Zip-in's® are made with a sophisticated heat treat process which allows the screw to taper to a fine, sharp point without sacrificing critical point strength

A single starting thread is formed down to the very tip of the point and is the source of Zip-in's® penetrating power

A second thread above the point engages after initial penetration and drills in the screw double fast

Malco's Zip-in® screws are faster driving, with a greater capacity for fastening heavier gauges of sheet metal than any other Self-piercing type
