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.
