YS Engine YSS1023 Replacement Insulator Screws 50 pcs  [YSS1023]

Engine mounting insulator screws overview

This 50-pack insulator screw kit is provided for modellers who require replacement or spare fasteners for engine mounts and associated fixtures. The screws are supplied as insulator-type replacements for use on model engines and related mounting points.

They act to isolate metal surfaces where insulation is necessary around RC engines and their fittings. The screws are suitable for replacing degraded fasteners or for retaining insulating washers and mounting hardware in the engine area.

Maintaining insulated mounting points during setup and tuning preserves reliable electrical separation between metal components and nearby electronics, making checks and troubleshooting quicker and more consistent.
