3.5mm x 16mm Torx Countersunk PT45 Screw for Hard Plastics | A2 Stainless Steel
For engineering plastics used in manufactured assemblies, this 3.5mm x 16mm Torx Countersunk 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 countersunk head keeps the assembly low profile.
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
- Manufactured Plastic Parts: Supports repeatable assembly of moulded hard-plastic components with correctly sized pilot holes and countersinks.
- Outdoor Equipment: Provides an A2 Stainless Steel fastening option for suitable exterior hard-plastic assemblies.
- Electrical Enclosures: Secures hard-plastic covers and panels where a countersunk surface finish is required.
- Appliance Housings: Provides a dedicated fastening method for rigid plastic covers, panels and moulded components.
