The 4.8mm diameter by 25mm length variant offers extended reach combined with robust diameter, making it ideal for applications requiring penetration through thicker materials or multiple layers whilst maintaining high strength characteristics. This configuration is particularly suited to insulated panel systems, composite materials, and situations where maximum thread engagement is critical. The 25mm length provides excellent versatility for varied material thicknesses, whilst the 4.8mm diameter ensures superior holding power under load. The self-drilling point efficiently cuts through materials without pre-drilling, significantly reducing installation time on larger projects. The zinc-plated finish provides reliable corrosion resistance for long-term performance. Features and Benefits: • 4.8mm diameter x 25mm length for thick materials and enhanced holding power • Ideal for insulated panels and composite material applications • Self-drilling point cuts efficiently through multiple la
