3mm x 8mm Pozi Countersunk PT45 Screw for Hard Plastics | A2 Stainless Steel
Suitable for outdoor hard-plastic equipment and housings, this 3mm x 8mm Pozi Countersunk screw uses the PT45 thread geometry intended for harder plastic components. The three-lobed thread body concentrates forming pressure at specific points while the countersunk profile allows the head to finish level with the surrounding surface.
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
- Polycarbonate Housings: Forms a secure thread in suitable polycarbonate covers and housings while allowing a flush head finish.
- Automotive Components: Fastens rigid plastic trim and moulded components where a low-profile screw head is beneficial.
- Manufactured Plastic Parts: Supports repeatable assembly of moulded hard-plastic components with correctly sized pilot holes and countersinks.
- Furniture Components: Secures suitable engineering-plastic fittings and panels used in furniture manufacture.
