4mm x 12mm Torx Countersunk PT45 Screw for Hard Plastics | A2 Stainless Steel
Ideal for outdoor equipment housings and rigid plastic panels, this 4mm x 12mm PT45 plastic screw is manufactured from A2 Stainless Steel with a Countersunk head and T15 Torx recess. The thread-forming profile displaces compatible plastic to create the mating thread without relying on conventional cutting action.
What Are Torx Countersunk PT45 Screws?
Torx Countersunk PT45 screws are designed for moulded or predrilled pilot holes in hard plastics and reinforced materials. The countersunk head provides a smooth low-profile finish while the Torx drive gives positive tool engagement for manual or automated assembly.
Common Applications
- 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.
- 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.
