4mm x 20mm Torx Pan PT45 Screw for Hard Plastics | A2 Stainless Steel
For engineering-plastic assemblies, this 4mm x 20mm Torx Pan PT45 Screw provides a purpose-designed alternative to a conventional self tapping screw. Its 45° trilobular thread supports reliable engagement in harder plastic bosses while the Torx drive helps reduce cam-out during installation.
What Are Torx Pan PT45 Screws?
Torx Pan 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. The Torx drive offers high contact area for efficient torque transfer.
Common Applications
- Consumer Electronics: Secures hard-plastic casings and internal components used in electronic products.
- Manufactured Plastic Parts: Supports repeatable assembly of moulded hard-plastic components with correctly sized pilot holes.
- Production Assemblies: Provides a high-contact Torx drive format for repeatable fastening into hard-plastic components.
- Electrical Enclosures: Secures hard-plastic covers, panels and housings used in electrical and control equipment.
