Compact Button Head Screws for RC Projects

The RADTEC RAD-AC-30001 M3x4mm aluminium button head screws offer a neat, lightweight fastening option for model racers and weekend tuners. These black screws are suited to general RC assembly where form and low mass are priorities.

Where to Use These Screws

These M3x4mm fasteners are ideal for securing servo mounts, body posts, and light brackets where aluminium upgrades are chosen to shave weight. Their shallow head profile reduces the chance of snagging on close-fitting parts.

Aluminium Hardware Benefits

Aluminium gives a favourable weight to strength ratio for many non-critical mountings. For applications that need the ultimate tensile strength, consider steel replacements for the highest load points.

Can I use these on carbon or aluminium chassis?

Yes, they work with carbon and aluminium parts provided the tapped holes are M3 and the depth suits a 4mm shank. Use washers where countersinking could weaken thin material.

Do these screws resist corrosion?

Aluminium does not rust like steel but can oxidise. For coastal or wet running keep fittings clean and consider protective coatings if needed.

Are these a direct swap for steel M3x4mm screws?

They are the same size but differ in strength. For non-structural swaps they are fine, but for load-bearing joints retain steel fasteners where appropriate.
