Ten 4 x 8mm hex socket set screws are supplied in this pack for RC-scale models where compact recessed fastening is needed. They provide a simple replacement option for worn fasteners and secure small parts during assembly and servicing. The hex socket design fits commonly used hobby hex drivers.
Fitting is straightforward: line up components, thread the set screw into the mating hole, and tighten with the correct hex driver until the part is held firmly without over-tightening. For repeat servicing, keep spare hex drivers to protect the socket from rounding. These fasteners help preserve consistent part alignment after teardown and setup changes.
