Dubro 3.5 x 20mm Socket Head Cap Screw Tool - DUB2273

The Dubro DUB2273 is a 3.5mm x 20mm socket head cap screw designed for use in RC aircraft assembly and repair. These M3.5 metric fasteners are a standard hardware item used across a wide range of RC models where a recessed hex socket drive offers a cleaner, more secure fix than a standard slotted or Phillips head screw. If you're replacing a stripped or lost screw on your aircraft or building a custom assembly, having the correct size on hand makes the job straightforward.
