Series 500 Metal Drilling screws

Series 500 Self Drilling Screws have a hardened extra long self drilling point which cuts through thick mild steel without the need for pre-drilling. The hex head enables a fast, secure drive into the steel and the fine cut thread allows for threading into thick steel. The galvanised coating is suitable for most outdoor applications. Series 500 screws are also known as S500 and No 5 Extended Self Drillers
