The Great Planes 2-56 x 1/2" Phillips Round Head Machine Screws – Zinc Plated (25 Pack) are reliable, high-quality fasteners perfect for RC airplanes, cars, boats, robotics, and general hobby projects. These screws are made to precise standards, giving builders the strength, consistency, and vibration resistance needed for dependable installations.

Each screw has a Phillips round head, which provides good tool grip and allows the screw to seat smoothly against your parts. The rounded head distributes pressure evenly, helping prevent damage to materials such as balsa, plywood, plastics, composites, and light metals. This makes them ideal for mounting servos, attaching control horns, installing electronics, securing engine components, and assembling custom parts.

The zinc-plated finish helps protect the screws from rust and corrosion, even in glow, gas, or electric setups where oil, fuel residue, or moisture may be present. The steel construction ensures lasting durability, even under high vibration or frequent maintenance.

Sold in a 25-pack, these machine screws are great for stocking your workshop or field box. Whether you're building a new model, upgrading components, or making quick repairs, these screws provide dependable fastening you can trust.
