4mm x 8mm Pozi Flanged PT45 Screw for Hard Plastics | A2 Stainless Steel
Developed for reinforced plastic parts used in demanding environments, this 4mm x 8mm Pozi Flanged Screw is part of the PT45 range for hard plastics. The trilobular 45° thread helps form a secure mating thread in compatible materials such as polycarbonate and fibre-reinforced plastics.
What Are Pozi Flanged PT45 Screws?
PT45 Pozi Flanged Screws use a three-lobed thread body that concentrates forming pressure around three points of the pilot hole. This geometry supports thread formation in harder plastics while the flange increases the bearing area beneath the head.
Common Applications
- Industrial Equipment: Fastens hard-plastic guards, covers and instrument housings on machinery and control equipment.
- Control Equipment: Fastens hard-plastic panels and housings used around sensors, switches and control systems.
- Fibre-Reinforced Plastics: Provides a specialised thread-forming fastening option for compatible reinforced plastic parts.
- Consumer Electronics: Secures hard-plastic casings and panels while distributing pressure over a larger local area.
