Specifications

Which one do I need?

At 15mm these are a short screw, ideal when there is very little depth to fix into, for example a fitting on a thin panel. A longer screw would risk coming through the far side. If the panel is thicker or the item is heavy, pick a longer length for more grip. Hold a screw against the panel edge first to confirm it will stay hidden.

How to use

1. Mark through the holes of the item you are fixing.
2. Use a bradawl or fine drill to start a hole in hard material.
3. Fit a small pozi bit that matches the recess.
4. Drive slowly and stop when the countersunk head is flush, as short screws strip easily.
