YS Engine YSS1004 Cylinder Head Screws 50pcs spare fasteners for RC engine heads  [YSS1004]

Cylinder head screws 50pcs

This 50pcs pack of cylinder head screws is a straightforward spare set intended for RC-scale glow and nitro engine maintenance. The fasteners serve as direct replacements when original screws are lost, worn, or stripped during disassembly.

Use these screws when rebuilding or servicing the cylinder head to maintain secure clamping between the head and crankcase. They are presented as general spare parts for hobby engines and are suitable for routine teardown, inspection, and tuning tasks that require reliable thread engagement.

When installing, verify thread condition in the crankcase and apply the correct torque for your engine size to avoid stripping threads or distorting the cylinder head. Keep the screws organised by length during disassembly so the head retains correct spacing and compression characteristics after reassembly.
