5mm x 20mm Pozi Countersunk PT45 Screw for Hard Plastics | Bright Zinc Plated Steel
Developed for instrument housings and control products, this 5mm x 20mm Pozi Countersunk Screw is part of the PT45 range for harder plastics. The trilobular 45° thread helps form a secure mating thread in compatible materials such as polycarbonate and reinforced plastics.
What Are Pozi Countersunk PT45 Screws?
PT45 Pozi Countersunk Screws use a three-lobed thread body that concentrates forming pressure around three points of the pilot hole. This geometry allows the screw to form a mating thread in harder plastics while the head can finish level with the surrounding component surface.
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.
- Prototype and Production Assemblies: Provides a specialist hard-plastic screw format for testing and repeat production fastening.
- Electrical Enclosures: Secures hard-plastic covers and panels where a countersunk surface finish is required.
