Yokomo YOKZCSS48 - 4 x 8mm Hex Socket Set Screw, 10pcs  [YOKZCSS48]

4 x 8mm set screw pack for RC use

This pack contains 10 pcs of 4 x 8mm hex socket set screws intended for RC-scale assemblies where compact, recessed fastening is required. The screws are supplied as a simple hardware option for replacing worn fasteners or keeping small components secured during setup and maintenance. The hex socket drive makes them compatible with standard hex drivers used in hobby workshops.

Installation is straightforward: align the components, insert the set screw into the threaded hole, and tighten with an appropriate hex driver until the part is held firmly without over-torquing. For repeated service or tuning work, keep a small selection of common hex drivers to prevent rounding the socket. These screws serve a tuning role by ensuring repeatable assembly positions after disassembly and rebuilds.
