We supply a number of options for coarse thread drywall screws: including phosphate coating, yellow zinc and clear zinc plating. Most notable is phosphate coated, providing an increase in corrosion resistance over clear zinc with 48 hour salt spray testing. Yellow zinc plating contributes to a shiny, golden appearance while still maintaining the same corrosion resistance as phosphate.
