Wider thread distance
Flat head PT@ thread screw is also known as Thread forming screw , it has a wider pitch and thinner threads compared to common tapping threads , this design increases shear areas and support a more good material flowing performance when it is installed .
◆ Harden material
◆ High tensile strength
◆ Fast thread drilling performance
◆ Good material flowing performance
◆ High clamping load performance
◆ Reduce radial stresses
d : thread diameter dk : head diameter
PT@ screws are normally used to secure plastics , there is a pre-drilling hole before install a screw , the hole diameter and depth are different for different plastic materials .
|Plastic material||Screw thread diameter “ d “||Pre-drilling hole diameter||Pre-drilling hole depth|
1 . Drill a pre-hole in material with pre-depth for screw ( see details in table )
2 . Insert screw into hole and screwing it in a wrench .
