Decking Screws 7g x 56mm SS. 500 screws
#7 x 56mm(2-1/4'')..Trim head Stainless screw.
These trim head screws are now available in Stainless steel with a type 17 tip. The trim heads were designed for architrave work where the screw could be driven into architraves instead of nails, thus avoiding the risk of damaging nicely shaped architraves. We now have them in stainless steel and they are now becoming popular for use on decks and are suitable for coastal and poolside applications. As the stainless is not as strong as the hardened steel care needs to be taken when driving and it may be necessary to pre drill
#1 is the driver bit size for #6 and #7 gauge screws
