Above codes & ETL for fasteners without washers.
Use a washer to seal head of fastener (make watertight) or as an isolator, or to increase pullover value. A washer must be fitted if a colour cap is to be used. A washer is also a good indicator of over/under driving.
See Fibre cement range for longer fasteners.
