F120 cylinder head mounting screws

This spare part supplies the mounting screws designated for the F120 cylinder head, sold under the YS Engine YSF1218 part number. The item is intended as a direct replacement fastener set for F120-series RC glow engines where the original screws are worn, stripped, or lost.

Installation: use the correct driver to avoid rounding the screw heads, tighten to the engine manufacturer's recommended torque values, and apply a removable threadlocker where specified for routine rebuilds. Inspect mating threads and head seats for damage before reuse.

Tuning and maintenance role: these screws secure the cylinder head to the crankcase and therefore are part of regular engine service and rebuild work; correct fastening prevents leaks and ensures consistent compression across runs.

Which engine models accept this screw set?

The YSF1218 screws are intended specifically for the F120-series cylinder head applications and are supplied as a replacement for those original fasteners.

Can damaged screws be reused after cleaning?

If screw heads or threads show wear or distortion, replacement is recommended rather than reuse. Clean components can be reused if the thread form and head seat remain in good condition.

Where do I find torque guidance for refitting?

Refer to the engine manufacturer's service manual for the correct torque values and any specific assembly instructions when reinstalling the cylinder head with replacement screws.
