This pack includes ten 4 x 8mm hex socket set screws designed for RC-scale assemblies where a low-profile recessed fastener is required. The screws act as a straightforward hardware option to replace worn parts or to keep small components secured during setup and maintenance. The hex socket drive is compatible with standard hobby hex drivers.
Installation is simple: align mating parts, insert the set screw into the threaded hole, and tighten with the correct hex driver until snug without over-torquing. For repeated service or tuning work, keep a set of common hex drivers on hand to avoid rounding the socket. These screws help maintain repeatable assembly positions after disassembly and rebuilds.
