Koswork 3x18mm Button Head Hex Hardened Steel RC Screw - KOSBS318

The Koswork KOSBS318 is a pack of eight M3 x 18mm button head hex hardened steel screws supplied in a convenient storage container. Designed for use in RC car builds and maintenance, these screws are a practical hardware addition for anyone working on M3 screw positions across chassis, body mounts, motor mounts, and similar assemblies. The low-profile button head style sits flush against surfaces where a standard pan or cap head would foul clearance, making them a sensible choice when space is tight.

Key Features

• M3 x 18mm specification — matches standard RC car hardware sizing for direct replacement or use in new builds
• Button head profile provides a lower seating height than cap head screws, useful in confined or clearance-sensitive locations
• Hardened steel construction offers greater resistance to stripping and wear compared to standard steel hardware
• Comes in a resealable container, keeping spares organised in a tool box or pit bag
• Pack of eight gives you enough to complete a full set of fixings in one go
