YS Engine YSS1023 Insulator Set Screws 50pcs  [YSS1023]

Insulator screws for model engines

This RC-scale insulator screw kit is supplied as a 50pcs service pack for hobbyists needing replacement or spare fasteners for engine mounts and nearby fixtures. The set gives a matched group of insulator-style screws intended for use on model engines and their mounting points.

These screws are general-purpose insulation fasteners that prevent metal-to-metal contact where electrical separation is required on RC engines and adjacent fittings. They are suitable when swapping out worn hardware or when securing insulating pads and mounting components in the engine bay.

During tuning and maintenance, keeping mounting points insulated helps preserve consistent electrical separation between metal parts and nearby electronics, which simplifies troubleshooting and routine checks before running the model.
