14g-20 x 22mm - 1000pc Hex Fine Self Drilling Screws Galvanised Class 4

Galvanised Hex 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 hex head enables a fast, secure drive into the steel. The galvanised coating is suitable for most outdoor applications.
