4mm x 16mm Torx Countersunk PT45 Screw for Hard Plastics | A2 Stainless Steel
Providing a dedicated fastening option for food and catering equipment components, this 4mm x 16mm Torx Countersunk PT45 Screw combines a 45° trilobular thread with A2 Stainless Steel. The countersunk head creates a low-profile finish while the Torx recess supports efficient torque transfer.
What Are Torx Countersunk PT45 Screws?
A Torx Countersunk PT45 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 where secure engagement, flush installation and a strong drive-to-strip ratio are required.
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 without leaving a prominent head above the surface.
