O.S. Engine OS79871555 M5 x 55 Hexagon Socket Head Cap Screw 10 Pack  [OS79871555]

M5x55 socket screw role in chassis setup

This listing for O.S. Engine OS79871555 describes ten M5x55 hexagon socket head cap screws supplied for RC-scale assemblies. The hex socket head allows precise torque control with a matching driver, useful when adjusting component positions during setup.

Installation notes: use a tight-fitting hex driver, apply measured torque and avoid overtightening which can distort mounting points. When fine-tuning, recheck fastener torque after initial running to ensure settings remain stable.

Tuning impact: these screws fasten engine mounts, motor and gearbox brackets; choosing the correct length and consistent head type helps keep suspension and drivetrain alignment predictable during setup changes and track use.
