Koswork 3x4mm Flat Head Hex Hardened Steel RC Screw Set - KOSFS304

The Koswork KOSFS304 is a set of M3 x 4mm flat head hex hardened steel screws, supplied in a convenient storage container, for use across a wide range of RC cars and buggies. Flat head hex screws of this size are commonly used for flush-fitting panels, chassis plates, and body mounts where a countersunk finish is required. The hardened steel construction gives these RC fasteners the strength to handle repeated removal and reinstallation without stripping.
