| forming screw used in metal .015 to .050 thick. Pro-Twist™ are tested to pierce 20 gauge steel or less |
Self-piercing needlepoint penetrates sheet metal from .0209 to .0358. Twin lead threads assure fast action and reduce driving torque and strip-out problems |
Thread forming screw used in light gauge steel for special applications requiring higher strip-out resistance |
Special designed point used to pre-drill and tap a hole in a one step application. Used in thicker gauge materials that would require a pre-drilled hole |

Spade Point |
Type 17 Point |
| Used for attaching ¾” to 1-1/8” materials to thin gauge steel. The leading blank shank eliminates thread engagement which is the primary cause of jacking |
Used for attaching 5/8 to 2-1/4 materials to thick gauge steel. The wings eliminate the need to pre-drill the attached material |
Primarily used to fasten cement board to wood or light gauge steel. The spade point penetrates the board without cracking |
Used for penetrating harder woods, eliminates splitting during installation. Can also be used in light gauge applications |
