The Yokomo ZC-SS43LA M4x3mm thread lock set screw is a small but effective fastener for RC builds. Its thread locking action is intended to keep small joints held together under running conditions.
Measuring 4 mm across and 3 mm long, this screw size helps avoid loosening caused by vibration. It is often used to lock the centre drive shaft on models like the YZ-4SF to maintain reliable drive engagement.
Five screws are included in the package, providing spare hardware for repairs or upgrades. Their compact form makes them handy for multiple RC applications where a secure small fastener is needed.
