YS Engine YSS1004 Cylinder Head Screw Kit 50pcs for RC Engine Maintenance  [YSS1004]

Cylinder head screw pack - 50 pcs

This 50pcs pack of cylinder head screws is a no-nonsense spare set designed for RC-scale glow and nitro engine maintenance. The fasteners are provided as replacements where original screws are lost, worn, or stripped during disassembly.

Apply these screws when rebuilding or servicing the cylinder head to maintain firm clamping between the head and crankcase. They are described as general spare parts for hobby engines and are suitable for normal teardown, inspection, and tuning tasks that need secure thread engagement.

Prior to installation, inspect crankcase threads and use the correct torque setting for your engine size to avoid thread stripping or head distortion. During disassembly, keep the screws organised by length so the head returns to the correct spacing and compression on reassembly.
