The Double Countersunk Hexalobular Six-Bevel Rib Milled Tail Chipboard Screw is a fastener engineered specifically for chipboard and wood-based panel connections. Featuring the specification 5.0-2.2*60, the 5.0mm outer thread diameter transitions to a 2.2mm core diameter over the 60mm thread length. It is manufactured from SUS304 austenitic stainless steel, known for its stable anti-corrosion properties. The surface undergoes a brightening treatment, resulting in a clean metallic finish. The head incorporates a double countersunk geometry to sit flush with the panel surface, while the hexalobular drive socket ensures efficient torque transmission without cam-out. Six longitudinally milled ribs on the shank enhance holding power within fibrous materials. The specialized milled tip acts as a cutting edge to facilitate chip evacuation, thereby reducing installation stress and minimizing the risk of material splitting. With an individual weight of 4.99 grams, it offers precise data for cost calculation and supply chain logistics.
