3.5mm x 10mm Torx Countersunk PT45 Screw for Hard Plastics | A2 Stainless Steel
Developed for consumer electronics and appliance housings, this 3.5mm x 10mm Torx Countersunk 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 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
- Automotive Components: Fastens rigid plastic trim and moulded parts where a low-profile screw head and Torx drive are beneficial.
- Industrial Equipment: Fastens hard-plastic guards, covers and instrument housings on machinery and control equipment.
- Outdoor Equipment: Provides an A2 Stainless Steel fastening option for suitable exterior hard-plastic assemblies.
- Fibre-Reinforced Plastics: Provides a specialised thread-forming fastening option for compatible reinforced plastic parts.

Key Benefits
- PT45 geometry provides a strong drive-to-strip ratio for compatible hard-plastic assemblies.
- Correct pilot-hole diameter, boss size and countersink geometry should be selected for the material being assembled.
- 3.5mm thread size and 10mm thread length provide the primary fastening dimensions.
- Trilobular geometry concentrates thread-forming pressure at three points rather than around a fully round profile.
