Self drilling screws for fixing into timber and thin steel thicknesses up to 0.75mm battens.
| 1. |
The thread on a Type 17 is parallel for constant clamp load. |
| 2. |
The drill point is sharp pointed and drills the timber to a pulp consistency. |
| 3. |
The special end slot forms a thread cutting action into the timber. The timber it cuts becomes
pulp like sawdust, which is distributed evenly into the open cell structure in the timber.
This becomes stabilised by the frictional heat generated while cutting, eliminating timber
expansion and minimising the splitting of timber. |
