4mm x 12mm Pozi Countersunk PT45 Screw for Hard Plastics | Bright Zinc Plated Steel
Commonly used for consumer electronics and appliance housings, this 4mm x 12mm 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?
A PT45 Countersunk screw provides a middle ground between a sharp 30° plastic thread and a conventional self tapping screw. Its shorter 45° thread and trilobular form make it particularly useful in hard materials where secure engagement and a strong drive-to-strip ratio are required.
Common Applications
- Automotive Components: Fastens rigid plastic trim and moulded components where a low-profile screw head is beneficial.
- Industrial Equipment: Fastens hard-plastic guards, covers and instrument housings on machinery and control equipment.
- Furniture Components: Secures suitable engineering-plastic fittings and panels used in furniture manufacture.
- Glass-Reinforced Plastics: Provides a specialised thread-forming fastening option for compatible reinforced plastic parts.
