Dubro Socket Head Cap Screw 3mm x 18 Tool - DUB2125

The Dubro DUB2125 is an M3 x 18mm socket head cap screw designed for use in RC aircraft builds, repairs, and mechanical assemblies. Dubro hardware is a long-standing staple in the RC hobby, and these metric fasteners are suited to securing servo mounts, control horns, motor mounts, and other structural components where a clean, recessed hex-drive finish is needed. The socket head profile allows tightening with an Allen key in tight spaces where a traditional screwdriver would struggle.
