◎ The suitability table below evaluates usage scenarios and buyer needs to help select the most appropriate fastener.
| Use case | Recommended product | Why |
|---|
| Thin wooden boards and trim work | Prox 4x35 mm | Shorter length and smaller diameter are ideal for lightweight and thin timber components. |
| Medium framing and general assembly | Prox 4.5x50 mm | Provides stronger holding power for medium-thickness joists and boards. |
| Thick beams and heavy timber framing | Prox 4.5x80/50 mm, Prox 4x70mm, or Prox 4.5x70 mm | Greater length ensures deep penetration and secure fastening in heavy structural lumber. |
| Large-scale construction projects | Prox 4x70mm or Prox 4x60 mm | Larger bulk packaging (250 pieces) is cost-effective for extensive building tasks. |
Prox Wood Construction Screw 4x35 mm is best suited for light woodworking, trim installation, and joining thinner timber elements where deep anchoring is not required. Choose this product if you are working on smaller-scale detailed projects. For heavy timber structures, thick beams, or large construction tasks, longer and thicker alternatives with appropriate bulk packaging will be a more suitable choice.
