1. ALWAYS know the thickness and type of base material into which you are
fastening. NEVER GUESS. Test the base material by using the Center Punch
Test. The Center Punch Test is performed by using a hammer to test drive the
particular power fastener to be used into the material. If the point penetrates
easily, the material is too soft. If the point becomes blunt, the material is too
hard. If the material fractures, cracks or shatters, the material is too brittle. Test
fastenings can be made if the material shows a clear fastener impression and
the fastener point is not blunted. Always start with the lowest powder load
(Gray-Level 1) and proceeding with the order shown in the lower right-hand
figure above. ALWAYS wear approved eye protection.
