Zinc Flat/Countersunk

Delivery or Click & Collect

These precision-engineered zinc-plated screws feature a flat, countersunk socket (Allen-drive) head—designed to sit flush with the surface for a clean, low-profile finish. They offer moderate corrosion resistance, making them ideal for general assembly, machinery, and fabrication tasks in non-harsh environments. Available in a comprehensive range of metric sizes (from M4×6 mm up to M12×120 mm, usually in 100-piece boxes), they’re supported by custom-cutting, technical guidance, and flexible fulfillment options across NSW and Australia.
