Description
| A dual thread screw ideal to secure IBR or corrugated sheeting to metal roof structures.
The dual thread shank drills through the IBR sheeting and at the point where it starts to drill through the metal structure below; the break in thread allows it to spin in the sheeting while it drills into the structure. The small top section of thread keeps the sheeting intact and prevents movement. |
Can be used for general metal construction due to the self cutting steel point.
Combined metal thickness should not be thicker than 5mm.
