Buying Guide
Threaded inserts for plywood vary by material, size, and installation method. Consider these factors to optimize performance:
- Material and corrosion resistance: Zinc or galvanized steel works well for most indoor plywood projects, while stainless variants are better for humidity-prone environments.
- Thread size and length: Match to your screw hardware and plywood thickness. Longer inserts provide stronger pull-out resistance but require deeper pre-drilled holes.
- Head design: Flushed vs. flanged heads influence surface finish and load distribution. Flanged designs help prevent pull-out on soft woods.
- Installation method: Hex drive tools enable straightforward seating; ensure your drill bit diameter matches the insert’s pilot hole requirement.
- Quantity and variety: Sets with multiple sizes reduce the need for separate purchases and support a range of joints in a single project.
- Application scope: For cabinetry and furniture repairs, prioritize inserts with robust holding power and easy reassembly capabilities.
