Metal to Metal: Self Drilling
Drilling capacity: 0.035″ – 0.210″
Thickness is based on normal, single thickness purlin/girt or multiple material thickness combined for total.
Minimum projection: 3/16″ of threads below substrate
Metal to Metal: Self -Tapping
Attachment thickness: 0.044″ – 0.075″
|METAL THICKNESS||DRILL SIZE|
|0.021 – 0.026||1/8″ (0.125 mm)|
|0.027 – 0.050||3/16″ (0.187 mm)|
|0.051 – 0.075||#8 (0.199 mm)|
The hole size determines installation strength and pullout strength.
Thickness is based on normal, single thickness purlin/grit or multiple material thickness combined for total.
Minimum projections: 3/8″ of threads below substrate.
