Precision Fasteners for Model Builders

Hobbyists looking for tidy, reliable fixings will appreciate these M3x40 countersunk Allen screws. They give a clean mounted appearance while holding components firmly in place.

Countersunk shape for low-profile mounting

The tapered head is designed to sit level with panels and bulkheads, reducing the chance of snagging on moving parts or interfering with aerodynamic surfaces.

Wide compatibility with common RC assemblies

The M3x40 length is a versatile option for a variety of model types, making these screws a useful item for both initial builds and later servicing.

Will these work on both cars and aircraft?

Yes, they are suitable for a range of RC platforms including cars and planes when the mating hole and countersink are prepared correctly.

Do they suit plastic and metal parts?

They can be used with both plastic and metal components; just avoid excessive torque on plastics to prevent deformation.

Are these finished to resist corrosion?

The original product notes steel construction for durability. For long life in harsh environments take standard precautions such as drying and inspecting after wet running.

Any tips for fitting countersunk screws?

Ensure the countersink matches the screw head so the screw sits flush, and use a driver that fits to avoid slipping or stripping.
