This product is a set of 2x6 mm button head screws commonly used as replacement or upgrade hardware for radio-controlled vehicles and other hobby projects. They are precision machined to standard metric size with a rounded button head that provides a smooth finish and distributes load over a larger surface area. These screws are suitable for securing plastic parts, electronics, and metal components where a low-profile head is needed. They are typically made from durable steel with a black oxide or similar coating to resist corrosion.
