The Hexagonal Large Flange Self-Tapping Screw is a fastener designed for connecting metal sheets and structural components. The specific specification, 12#-14*55, denotes a fine-pitch American standard thread (#12-14) that ensures reliable locking force, with a 55mm threaded length. Manufactured from SUS410 martensitic stainless steel, this screw offers robust mechanical strength and inherent corrosion resistance. Its surface is treated with Dacromet coating, a chromium-free, zinc-aluminum flake finish that provides exceptional barrier protection against salt spray and is capable of withstanding high operational temperatures. The integrated large flange design increases the bearing surface, delivering superior clamping force while minimizing the risk of deforming the fastened materials. With a single-unit weight of approximately 8.78 grams, it provides precise data for logistics and inventory planning.
