This M2.6x5 hexagon socket head cap screw is an RC-scale hardware item supplied by O.S. Engine as model OS79871010, sold in a pack of 10 pcs. It is intended for use in small assemblies where a compact, recessed-head fastening is required, such as engine hardware mounting, linkages, and chassis brackets on model-scale vehicles.
Design focus is on consistent thread sizing and head profile so you can replace worn or lost fasteners without changing fit or alignment. The screw's M2.6 dimension is stated in the product name and should be matched to existing tapped holes and nuts in your RC components to maintain proper clamping and clearance.
When selecting replacements, confirm thread engagement and length against the original part to avoid overrun into internal components or insufficient thread depth. These screws are supplied in a practical quantity for routine maintenance and small rebuild tasks.
