YS Engine YSS1004 50-Piece Cylinder Head Screw Set for RC Engines  [YSS1004]

50-piece cylinder head screw set

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

Fit these screws when servicing or rebuilding the cylinder head to ensure secure clamping between the head and crankcase. They are supplied as general spare parts for hobby engines and are suitable for routine teardown, inspection, and tuning jobs that need dependable thread engagement.

During installation, check the crankcase thread condition and apply the correct torque for your engine size to avoid stripping threads or warping the cylinder head. Keep screws organised by length while disassembling so the head retains proper spacing and compression after reassembly.
