5mm x 25mm Pozi Flanged PT45 Screw for Hard Plastics | Bright Zinc Plated Steel
Built for polycarbonate mouldings and rigid plastic components, this 5mm x 25mm PT45 Screw uses a Flanged head, PZ2 Pozi drive and Bright Zinc Plated Steel construction. The specialist thread form is intended for harder plastics where a strong drive-to-strip ratio and a wider bearing surface are useful.
What Are Pozi Flanged PT45 Screws?
Pozi Flanged PT45 screws are designed for moulded or predrilled pilot holes in hard plastics and reinforced materials. The Pozi recess uses a widely available drive format while the wide head diameter distributes clamping pressure across more of the component surface.
Common Applications
- Consumer Electronics: Secures hard-plastic casings and panels while distributing pressure over a larger local area.
- Manufactured Plastic Parts: Supports repeatable assembly of moulded hard-plastic components with correctly sized pilot holes.
- Production Assemblies: Provides a specialist PT45 fastener for repeatable assembly where the flange helps spread clamping stress.
- Electrical Enclosures: Secures hard-plastic covers and panels where a wider bearing head helps distribute clamping load.

Key Benefits
- Correct pilot-hole diameter, boss size and engagement length should be selected for the material being assembled.
- 9.60mm head diameter gives the Flanged head a broad bearing surface.
- Trilobular geometry concentrates thread-forming pressure at three points rather than around a fully round profile.
- The wider range also includes Bright Zinc Plated Steel, Black Zinc Plated Steel and A2 Stainless Steel options.
