Lightweight 7075 Countersunk Fasteners for RC

Picking suitable screws influences both performance and service life of your model. The Arrowmax AM-14CS3008-B Aluminium Screw Allen Countersunk M3x8 Blue (7075) is engineered to cut weight while retaining secure fastening for common hobby tasks.

Advantages of 7075 aluminium hardware

7075 aluminium offers an excellent strength-to-weight balance compared with softer alloys. The countersunk profile allows parts to sit flush, which helps with aerodynamics and neat assembly work.

Practical uses on models

These M3x8 countersunk screws are ideal for attaching bodywork, interior mounts and other areas where a low-profile finish is preferred. The blue finish simplifies part sorting and quick checks during pit-side fixes.

Can I use these on metal-to-metal joints?

Yes for many metal joints, but match thread engagement and consider locking compound for vibration-prone areas. For highly stressed metal joints check material compatibility first.

Is the blue anodising likely to wear off with frequent maintenance?

Anodising resists wear better than plain aluminium, but repeated heavy contact or abrasive cleaning can dull the finish over time. Handle with appropriate tools to preserve the coating.

What size driver should I use for these Allen screws?

Use the matching M3 Allen key or driver bit sized for countersunk sockets and apply firm, controlled torque to avoid rounding. Manual tightening is often safest.
