7075 Aluminium M3x8 Countersunk Screws for RC Assembly

Choosing the right fasteners affects durability and handling of your RC models. The Arrowmax AM-14CS3008-B Aluminium Screw Allen Countersunk M3x8 Blue (7075) gives hobbyists a balance of low mass and strong clamping for routine builds and upgrades.

Why aluminium works well for model builds

Aluminium fasteners made from 7075 are prized for a strong strength-to-weight ratio, letting you cut mass without sacrificing joint integrity. The countersunk head sits flush to help preserve body lines and reduce snag points on scale surfaces.

Best applications in RC projects

These M3x8 countersunk screws are suited to securing panels, interior braces and trim where a smooth finish is needed. The blue anodised finish also makes them easier to spot during assembly and maintenance.

Are these M3x8 screws safe to use on plastic parts?

They can work with plastic if you use the correct torque and avoid over-tightening. For soft plastics consider using a washer or a threadlocker designed for plastic to reduce stress.

Will 7075 aluminium hold up in high-stress mounting points?

7075 is strong for aluminium and performs well in many load-bearing spots, but for extreme shear or impact points stainless steel may be more appropriate. Use these screws where weight savings matter.

How do I avoid stripping the heads when installing these screws?

Use a correctly sized Allen key and steady pressure, and stop once the head is flush. Avoid power drivers on high torque settings to prevent rounding the socket.
