Buying Guide
Choosing screws for plastic involves balancing material compatibility, fastening strength, and ease of use. Consider the following factors to select the right kit for your project.
- Material and corrosion resistance: For plastic projects that contact moisture or outdoor environments, stainless steel (especially 410 stainless) offers corrosion resistance and durability. Carbon steel with galvanization provides strong performance at a lower cost, but may rust in very humid or outdoor conditions.
- Head style and drive: Pan heads and truss/wafer heads offer broad bearing surfaces and reduced pull-through in softer plastics. Phillips drives are common; for smaller electronics or tight assemblies, cross recessed heads help with precise alignment.
- Size, length, and thread type: For plastic, start with small diameters like #8 and lengths from 1/2″ to 1″ for general mounting. Self-tapping designs work well in softer plastics, while pre-drilling may still be advisable for hard plastics to prevent cracking.
- Packaging and organization: Sets that include a clear organizer box save time and reduce search frustration on projects with multiple sizes.
- Application compatibility: If you’re joining plastic to metal or wood, a mixed set that includes several sizes ensures you have a fastener that matches the material thickness and hole size.
- Tool compatibility: Ensure your drill or driver bit matches the screw drive (Phillips or cross recessed) and that your tool’s torque is appropriate to avoid stripping or cracking plastic.
Quick Comparisons For Plastic Projects
