3mm x 20mm Pozi Countersunk PT45 Screw for Hard Plastics | A2 Stainless Steel
Offering a thread-forming solution for external plastic fixtures, this 3mm x 20mm PT45 Screw combines a Countersunk head with a PZ1 Pozi recess. The A2 Stainless Steel fastener uses a shorter 45° thread and trilobular body to suit compatible hard plastics and reinforced materials.
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
- Prototype and Production Assemblies: Provides a specialist hard-plastic screw format for testing and repeat production fastening.
- Electrical Enclosures: Secures hard-plastic covers and panels where a countersunk surface finish is required.
- Industrial Equipment: Fastens hard-plastic guards, covers and instrument housings on machinery and control equipment.
- Control Equipment: Fastens hard-plastic panels and housings used around sensors, switches and control systems.
