3.5mm x 20mm Torx Countersunk PT45 Screw for Hard Plastics | A2 Stainless Steel
Offering a thread-forming solution for polycarbonate mouldings and reinforced plastic components, this 3.5mm x 20mm PT45 Screw combines a Countersunk head with a T10 Torx recess. The A2 Stainless Steel fastener uses a shorter 45° thread and trilobular body to suit compatible hard plastics and reinforced materials.
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
- Consumer Electronics: Secures hard-plastic casings and panels without leaving a prominent head above the surface.
- Manufactured Plastic Parts: Supports repeatable assembly of moulded hard-plastic components with correctly sized pilot holes and countersinks.
- 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.
