3.5mm x 8mm Pozi Countersunk PT45 Screw for Hard Plastics | A2 Stainless Steel
Suitable for food and catering equipment components, this 3.5mm x 8mm Pozi Countersunk screw uses the PT45 thread geometry intended for harder plastic components. The three-lobed thread body concentrates forming pressure at specific points while the countersunk profile allows the head to finish level with the surrounding surface.
What Are Pozi Countersunk PT45 Screws?
PT45 Pozi Countersunk Screws use a three-lobed thread body that concentrates forming pressure around three points of the pilot hole. This geometry allows the screw to form a mating thread in harder plastics while the head can finish level with the surrounding component surface.
Common Applications
- Appliance Housings: Provides a dedicated fastening method for rigid plastic covers and moulded appliance parts.
- Lighting Products: Secures rigid plastic bezels, covers and housings where a flush finished face is useful.
- Polycarbonate Housings: Forms a secure thread in suitable polycarbonate covers and housings while allowing a flush head finish.
- Automotive Components: Fastens rigid plastic trim and moulded components where a low-profile screw head is beneficial.

Key Benefits
- PT45 geometry provides a strong drive-to-strip ratio for compatible hard-plastic assemblies.
- Correct pilot-hole diameter, boss size and countersink geometry should be selected for the material being assembled.
- 3.5mm thread size and 8mm thread length provide the primary fastening dimensions.
- Trilobular geometry concentrates thread-forming pressure at three points rather than around a fully round profile.
