What Are Torx Countersunk PT45 Screws?
Torx Countersunk PT45 Screws are thread-forming fasteners developed for harder plastics. Their 45° trilobular thread has shorter flanks than PT30 screws and is suited to materials such as polycarbonate and fibre-reinforced plastics while the countersunk head allows a flush installation into a matching recess.
Common Applications
- Food and Catering Equipment: Supports suitable rigid-plastic assemblies where corrosion-resistant A2 Stainless Steel is preferred.
- 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.
