A high‑strength M3 x 15 mm countersunk screw made from premium Grade 12.9 alloy steel with a black finish ideal for flush‑mount fastening in mechanical, robotics, electronics, and precision‑engineering projects. The flat hex socket head sits flush with the surface for a clean, low‑profile look, while the hex drive allows secure tightening with an Allen key. Built for durability and maximum tensile strength, this screw is well-suited for applications where reliability and load‑bearing capability matter.
