RC-grade Countersunk Fasteners

These M3x40 countersunk Allen screws provide a tidy, low-profile fixing for model construction and upkeep. They are suited to applications where a flush mount is preferred.

Designed to minimise snagging

The countersunk head reduces protrusion above surfaces, helping to prevent catches on chassis, bodies and control linkages during operation.

Reliable length and fit for many models

M3x40 is a common size for a variety of RC parts, making these screws a practical choice for builders and for routine maintenance spares.

Will these work in metal bulkheads?

Yes, they are suitable for metal and similar rigid components when used with the correct pilot hole and counterbore to match the head.

Is over-tightening a common issue?

Over-tightening can damage threads or deform softer materials, so tighten to a firm but controlled level and check fit regularly.

How should I store spare screws?

Keep them dry and organised in a parts tray to avoid corrosion and to make selection quick during build sessions.
