2-56 x 1/2" Phillips Round Head Machine Screws – Zinc Plated, 25 Pack (Great Planes) | RC Hardware

The Great Planes 2-56 x 1/2" Phillips Round Head Machine Screws – Zinc Plated (25 Pack) offer dependable, high-quality fastening for RC aircraft, cars, boats, robotics, and a wide range of hobby and workshop projects. Designed for modelers who need strength, corrosion resistance, and consistency, these screws are manufactured to precise tolerances to ensure secure, vibration-resistant installations.

Each screw features a Phillips round head, providing excellent tool engagement while allowing smooth seating on servo mounts, control horns, engine components, servo trays, electronics housings, and custom assemblies. The round head profile offers a clean, finished appearance and distributes pressure evenly, reducing the risk of material damage—ideal for balsa, ply, composites, plastics, and light metals.

The zinc-plated finish enhances corrosion resistance, making these screws suitable for glow, gas, and electric RC environments where exposure to fuel residue, oil, and moisture is common. The strong steel construction ensures long-lasting durability, even under high-vibration flight conditions or repeated maintenance cycles.

Packaged in a convenient 25-piece set, these 2-56 x 1/2" machine screws are perfect for stocking your field box or workshop, providing the reliability needed for new builds, upgrades, or repairs. Whether you're assembling a precision control system, mounting onboard electronics, or performing routine maintenance, Great Planes machine screws deliver the secure fastening performance trusted by RC hobbyists for decades.
