MACSIM 12G-11x75mm TYPE 17 Screw Square Galvanised 50Pcs 17GSCD12075

The MACSIM 12G-11x75mm TYPE 17 Screw delivers professional-grade fastening specifically engineered for metal-to-timber applications. Featuring the innovative Type 17 self-drilling point, these screws eliminate the need for pre-drilling, cutting their own pilot hole as they're driven through metal and into timber substrates—saving significant time and effort on installation projects.

Designed with a countersunk self-embedding head that sits flush with the surface, these screws create a clean, streamlined finish ideal for metal roofing, cladding, batten installation, and structural steel-to-timber connections. The Class 3 galvanised finish provides superior corrosion resistance for outdoor and coastal applications, ensuring long-lasting performance in harsh Australian conditions. The square drive (#3) offers excellent torque transfer and reduced cam-out compared to Phillips drives, making installation faster and more reliable with power tools. At 75mm in length with 12-gauge thickness, these screws deliver the strength and penetration needed for demanding structural applications.
