Macsim Class 4 Galvanised Hex Head Self Drilling Screws are heavy-duty, high-performance fasteners designed specifically for structural steel-to-metal or steel-to-wood applications. They feature an integrated drill-shaped point that cuts through metal substrates effortlessly, completely eliminating the need for pilot holes
Key Specifications & Features
- Class 4 Galvanised Coating: Provides maximum corrosion resistance. It is engineered for harsh outdoor environments, industrial settings, and coastal areas.
- Hex Head Design: Features a hex flange or hex washer face (HWF) that provides enhanced socket grip and high torque transmission.
- Optional Neoprene Washer: Many variants include a pre-assembled neoprene sealing washer. This creates a water-tight seal to prevent moisture entry and long-term corrosion.
- Drive Sizes: Typically uses a 5/16" hex socket drive for 10G and 12G screws, or a 3/8" hex socket drive for 14G screws.
Application Guide
- Metal to Metal: Ideal for framing, sheeting, gates, carports, and steel cladding.
- Roofing & External Cladding: Variants equipped with a neoprene washer must be used for roofing to prevent leaks around the puncture point.
- Industrial & Marine: The Class 4 mechanical galvanisation layer stands up to high atmospheric salinity and industrial chemical residue
