TRF421/X 3x2.6mm Hex Step Screw, model spare set

The TRF421/X 3x2.6mm Hex Step Screw set is a dedicated spare set for model maintenance, built around an exact fastening format rather than a generic replacement. With 4 matching screws in 3x2.6 mm, it supports repair work where the specified size needs to be retained for the original assembly layout. The hex step screw form matters in use because it combines the fastening function with a defined shoulder profile, making it suitable for connection points that depend on this exact geometry. Keeping the stated 3x2.6 mm size avoids guesswork during servicing and helps maintain consistency across repeated repairs. The 4-piece count also makes the set practical for replacing worn or missing hardware while keeping identical spares on hand for later workshop jobs. On the bench, this set fits the kind of maintenance routine where small hardware needs to match the original specification closely. It suits model builders who sort parts by size and type, and it gives existing assemblies a straightforward way to be refitted with the correct screw format after disassembly or wear.
