YS Engine YSS1023 50pc Insulator Screw Pack  [YSS1023]

Engine mount insulator screw kit

This 50-piece insulator screw pack is aimed at hobbyists who need a ready supply of replacement fasteners for engine mounting and associated fixtures. The screws are grouped as insulator-type replacements for model engine mounting points.

They function to isolate metal-to-metal contacts where insulation is required around RC engines and adjacent fittings. Use them to replace degraded fasteners or to secure insulating washers and mounting components in the engine compartment.

Keeping mounting points insulated during routine work can reduce electrical interference between metal parts and nearby electronic components, making setup checks and troubleshooting more straightforward.
