Description
CSI Spiral Drive Pins are designed for permanently fastening a fixture to concrete, concrete over
steel deck, concrete masonry walls and A36 or A572 / A992 structural steel. The fasteners are
manufactured with an 8mm head and 0.157" diameter shank in various lengths; a 0.145" diameter
tapered shank with 1/2-inch length is also available. A spiral knurled shank design provides
consistent optimized performance in steel base materials. For single fasteners, a plastic washer
is mounted on the pin shank to retain the drive pin in the barrel of the tool and provide centered
guidance during the driving operation. The fasteners are also available in collated strips.
