3.5mm x 10mm Pozi Countersunk PT45 Screw for Hard Plastics | A2 Stainless Steel
Providing a dedicated fastening option for external plastic fixtures, this 3.5mm x 10mm Pozi Countersunk PT45 Screw combines a 45° trilobular thread with A2 Stainless Steel. The design is well suited to harder plastics while the countersunk head provides a neat flush fit where the component has a matching recess.
What Are Pozi Countersunk PT45 Screws?
Pozi Countersunk PT45 Screws are thread-forming fasteners developed for harder plastics. Their 45° trilobular thread has shorter flanks than PT30 screws and is better suited to materials such as polycarbonate and glass-reinforced plastics while the countersunk head allows flush installation into a matching recess.
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.
