For general metal construction due to the self drilling steel point.

Ideal for metal to metal installations.

The drilling point must be long enough to completely drill through the material before the threads engage.

If the drilling point is too short and threads engage too early, the fastener can stop drilling and the head can break off.

The combined metal thickness should not be thicker than 5mm.

The product requires a power tool and a nutsetter to complete installation.

Drill slower than 1,500 rpm.

Hold the power drill at a 90 degree angle.

Do not drill the tek screw through a welded joint.

Can be used to secure IBR or Corrugated roof sheeting to metal roof structures.

The ideal Tek screw to use for roofing installations is the Dual Thread Tek screw.
