C-5 Self-Drilling Screw
C-5 Self-Drilling Screw. The cover is directly screwed to the conveyor structure.
No pre-drilling is needed. This high-quality screw drills easily up to 12 mm. (0.50 in.) of steel structure by itself. It can be unscrewed for opening the cover and screwed back many times. The neoprene washer included will avoid corrosion into the drilled structure.
