3.5mm x 12mm Pozi Countersunk PT45 Screw for Hard Plastics | A2 Stainless Steel
Developed for external plastic fixtures, this 3.5mm x 12mm Pozi Countersunk Screw is part of the PT45 range for harder plastics. The trilobular 45° thread helps form a secure mating thread in compatible materials such as polycarbonate and reinforced plastics.
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
- Appliance Housings: Provides a dedicated fastening method for rigid plastic covers and moulded appliance parts.
- Lighting Products: Secures rigid plastic bezels, covers and housings where a flush finished face is useful.
- 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.
