4mm x 25mm Pozi Pan PT30 Screw for Soft Plastics | Black Zinc Plated Steel
Developed for commercial plastic components where a dark finish is preferred, this 4mm x 25mm Pozi Pan Screw is part of the PT30 range for soft plastics. The 30° flank geometry increases thread engagement while reducing outward loading on the plastic boss and the PZ2 recess supports straightforward installation.
What Are Pozi Pan PT30 Screws?
Pozi Pan PT30 Screws use a narrow 30° thread flank with a relatively small minor diameter to improve material engagement in plastic bosses. This geometry helps reduce installation torque and outward stress while the Pan head provides a broad bearing surface above the assembled component.
Common Applications
- Prototype and Production Assemblies: Provides a specialist plastic screw format for testing and repeatable production fastening.
- Consumer Electronics: Fastens plastic casings, covers and internal supports used in electronic products.
- Industrial Equipment: Provides thread-forming fastening for plastic guards, covers and instrument housings.
- Manufactured Plastic Parts: Supports repeatable assembly of injection-moulded components with correctly designed pilot holes.
