Flush Screw Seating with 3Racing Aluminium M4 Countersink Washers

Model builders seeking clean, low-profile fixes will appreciate the 3Racing Aluminium M4 Countersink Washers. They are designed to pair with countersunk screws to leave a smooth outer surface and reduce the chance of snagging on obstacles.

Material Benefits for Hobby Builds

Aluminium delivers a good strength-to-weight ratio, important for keeping handling predictable. The red anodized finish helps resist corrosion from moisture and salt exposure from outdoor running.

Common Applications in RC Models

These washers fit M4 countersunk configurations and are suitable for fastening body shells, mounting internal panels, or areas that must remain flush to avoid interference.

Are these compatible with alloy and plastic panels?

Yes, they work with both metal and plastic panels; ensure the screw length and panel thickness provide enough thread engagement for a secure joint.

Will the anodised finish wear off quickly under use?

The anodised layer is durable for normal use, though it can be abraded by aggressive tools or repeated disassembly; handle with care during maintenance.

Can these help prevent screw rotation in thin panels?

They provide a larger bearing surface which can reduce screw pull-through and rotation; for very thin panels consider additional backing or a washer stack.
