3.5mm x 8mm Torx Countersunk PT45 Screw for Hard Plastics | A2 Stainless Steel
Manufactured for fastening automotive interior plastic components, this 3.5mm x 8mm PT45 Screw for Hard Plastics features a Countersunk head, T10 Torx drive and A2 Stainless Steel construction. Its trilobular 45° thread is designed for secure engagement in harder plastic bosses while the head finishes level with the surrounding surface.
What Are Torx Countersunk PT45 Screws?
PT45 Torx Countersunk Screws use a three-lobed thread body that concentrates forming pressure around three points of the pilot hole. This geometry supports thread formation in harder plastics while the Torx recess provides high contact area for efficient torque transfer.
Common Applications
- 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.
- Control Equipment: Fastens hard-plastic panels and housings used around sensors, switches and control systems.
- Polycarbonate Housings: Forms a secure thread in suitable polycarbonate covers and housings while allowing a flush head finish.
