5mm x 25mm Pozi Countersunk PT45 Screw for Hard Plastics | Bright Zinc Plated Steel
Commonly used for instrument housings and control products, this 5mm x 25mm PT45 plastic fastener features a Countersunk head and PZ2 Pozi drive. The Bright Zinc Plated Steel screw forms its thread within a suitably designed moulded or predrilled pilot hole and finishes flush when installed into a matching countersink.
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
- 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 and moulded appliance parts.
- 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.
