10g-24 x 50mm - 500pc Galvanised Countersunk Fine Self Drilling Screws

Galvanised Countersunk Fine Self Drilling Screws have a hardened self drilling point which cuts through mild steel without the need for pre-drilling. However for thick or hardened steel pre-drilling may be required. The countersunk head allows the screw to sit flush and the galvanised coating is suitable for most outdoor applications.
