Drive pins with a 0.3 in Dia head 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 a 0.145 in Dia shank in various lengths. Knurled shank designs are available for installations in thick steel base materials. A plastic flute is mounted on the pin shank to retain the drive pin in the barrel of the tool and provide guidance during the driving operation.
