10g-16 x 16mm - 1000pc Hex Coarse Self Drilling Screws with EPDM Washer Galvanised Class 4

Galvanised Hex Coarse Self Drilling Screws with Neo 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 and the coarse thread is ideal for fastening to sheet metal or other thin steel. The Neo washer helps give a water tight seal and the galvanised coating is suitable for most outdoor applications.
