4mm x 20mm Pozi Flanged PT45 Screw for Hard Plastics | A2 Stainless Steel
Suitable for reinforced plastic parts used in demanding environments, this 4mm x 20mm Pozi Flanged screw uses the PT45 thread geometry intended for hard plastic components. The three-lobed thread body concentrates forming pressure at specific points while the 8.00mm head diameter provides a broad bearing face above the component.
What Are Pozi Flanged PT45 Screws?
A PT45 Flanged 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 harder materials while the wide flange supports broader load distribution.
Common Applications
- Furniture Components: Secures suitable engineering-plastic fittings and panels used in furniture manufacture.
- Fibre-Reinforced Plastics: Provides a specialised thread-forming fastening option for compatible reinforced plastic parts.
- Appliance Housings: Provides a dedicated fastening method for rigid plastic covers, panels and moulded components.
- Lighting Products: Secures rigid plastic bezels, covers and housings where a broad bearing surface is beneficial.
