The IRWIN Hex Countersink in 16mm is the largest size in the range, specifically designed for heavy-duty applications and larger gauge screws commonly used in construction, structural work and robust joinery projects.
This substantial size makes it the go-to choice for decking, pergolas, timber framing and other applications where larger fixings are required.
