RC 10-Pack 4 x 8mm Hex Socket Set Screws - Yokomo YOKZCSS48  [YOKZCSS48]

4x8mm hex screws — hobby 10-pack

This 10-pack contains 4 x 8mm hex socket set screws aimed at RC hobby use where compact recessed fastening is required. They are an easy option for replacing fatigued fasteners and for securing small parts during setup, repair, or tuning. The hex socket accepts standard hobby hex drivers for convenience in the workshop.

To install, position the parts, insert the set screw into the threaded hole, and tighten with an appropriate hex driver until the joint is secure without applying excessive torque. Keeping a selection of hex drivers helps prevent socket rounding during repeated tuning adjustments. These screws support consistent assembly geometry after disassembly and rebuilds.
