The GPM SUS2.5X15 cap head socket screws are delivered as a 20-piece set of M2.5x15mm fasteners in SUS304 stainless steel. SUS304 provides corrosion resistance and stable mechanical properties suitable for long-term use in model assemblies. Use these screws for secure mechanical joins, replacement of worn hardware and standardising fastener sizes across an RC platform. For installation, match the M2.5 hex driver to the socket head and apply controlled torque to avoid thread damage while ensuring firm clamping.
