Koswork 4x14mm Button Head Hex Hardened Steel RC Screw - KOSBS414

The Koswork KOSBS414 is a set of M4 x 14mm button head hex screws made from hardened steel, suited to RC car builds and repairs where a low-profile screw head and strong clamping force are needed. These are a practical hardware addition for RC builders who want reliable fasteners on hand, particularly when working on chassis, body mounts, or component brackets that call for M4 sizing.

Key Features

• Hardened steel construction provides greater resistance to stripping and shear force compared to standard mild steel screws
• Pack of 8 screws supplied in a storage container, keeping spares organised in the workshop or pit bag
• M4 thread sizing is commonly used across many 1/8 and 1/10 scale RC car platforms for chassis and component fastening
